Why the torque is maximum when the plane is horizontal and falls to zero when it is vertical?
Torque is maximized when the plane is horizontal because the force due to gravity acts perpendicularly to the lever arm, resulting in the greatest rotational effect. As the plane tilts towards a vertical position, the angle between the force of gravity and the lever arm decreases, leading to a reduction in torque. When the plane is completely vertical, the force of gravity acts parallel to the lever arm, causing the torque to drop to zero. Thus, the orientation directly influences the effectiveness of the force in creating rotational motion.
Is angular acceleration proportional or inversely proportional to torque?
Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).

What is differential equation of spring mass system attached to one end of seesaw?
The differential equation for a spring-mass system attached to one end of a seesaw can be derived from Newton's second law. If the mass ( m ) is attached to a spring with spring constant ( k ), the equation of motion can be expressed as ( m\frac{d^2x}{dt^2} + kx = 0 ), where ( x ) is the displacement from the equilibrium position. Additionally, if the seesaw is rotating, the dynamics will involve torque and may require considering angular motion, but the basic oscillatory behavior remains governed by the spring-mass dynamics. The overall system would likely result in a coupled differential equation incorporating both linear and rotational dynamics.
What is an Inch Pound Equation?
An inch-pound equation refers to a formula that expresses a relationship between torque, force, and distance in the inch-pound system of measurement. In this system, torque is typically calculated by multiplying the force applied (in pounds) by the distance from the pivot point (in inches). The resulting torque is measured in inch-pounds (in-lbs). This equation is commonly used in mechanical and engineering applications to analyze rotational forces.
Rotational tendency of force?
The rotational tendency of a force is referred to as torque. Torque is the measure of the force's effectiveness at rotating an object and is calculated as the product of the force applied and the lever arm distance from the axis of rotation. It is a vector quantity that determines the rotational motion of an object.
What role does torque play in the rotational motion of machines?
Torque is the rotational equivalent of force, responsible for causing an object to rotate around an axis. In machines, torque is pivotal for providing the necessary power to drive the rotational motion of components like shafts, gears, and pulleys. The magnitude of torque determines the acceleration or deceleration of rotational motion in machines.
The product of an object's rotational inertia and its rotational velocity is?
The product of an object's rotational inertia and its rotational velocity is called angular momentum. It is a conserved quantity in a closed system, meaning it remains constant unless acted upon by an external torque.
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
What is the relationship between the direction of torque and the rotational motion of an object?
The direction of torque determines the direction of rotational motion of an object. Torque is a force that causes an object to rotate around an axis, and the direction of the torque applied determines the direction in which the object will rotate.
What is the rotational analog of force in linear motion?
Torque is the rotational analog of force in linear motion. It represents the force that causes an object to rotate around an axis. Just as force is required to accelerate an object in a straight line, torque is required to rotate an object.
What is the relationship between the net torque acting on an object and its resulting rotational motion?
The net torque acting on an object determines its resulting rotational motion. If the net torque is greater, the object will rotate faster, and if the net torque is smaller, the object will rotate slower.
What is the relationship between the torque on a pulley with mass and its rotational motion?
The torque on a pulley with mass affects its rotational motion by determining how quickly it accelerates or decelerates. A greater torque will cause the pulley to rotate faster, while a smaller torque will result in slower rotation.
What is the rotational work formula and how is it used to calculate work done in rotational motion?
The rotational work formula is W , where W represents the work done in rotational motion, is the torque applied, and is the angle through which the object rotates. This formula is used to calculate the work done in rotational motion by multiplying the torque applied to an object by the angle through which it rotates.
What is torque and state the conditions of rotational equilibrium?
Torque is analogous to force. As Force produces a change in the state of linear motion of a body, Torque produces a change in the state of rotational motion of a body. The unit is newton meter (Nm) and the symbol is tau (τ) For rotational equilibrium, the algebraic sum of the torques acting on a body must be zero. ie. Στ=0
How is torque related to angular acceleration in rotational motion according to the equation torque I alpha?
In rotational motion, torque is directly related to angular acceleration through the equation torque moment of inertia angular acceleration. This means that the amount of torque applied to an object will determine how quickly it accelerates in its rotation.
What is the significance of the sign of torque in rotational motion?
The sign of torque in rotational motion indicates the direction of the force causing the rotation. It is important because it determines whether the rotation is clockwise or counterclockwise, and helps in understanding the overall motion and stability of an object.
