State and explain Theorem of transmissibility of forces?
states that the external effect of force are independent of the point of application of the force along its line of action.
What is the mechanical advantage of a wheel and axle mechanism in which the radius of the axle supporting the load is 6 inches and the diameter of the drum to which the force is applied is 24 inches?
4
What pressure is created when 5.0 N of force are applied to an area of 2.0 m to the second power?
5/2 = 2.5 Newtons per square meter = 2.5 Pascals
Does the average speed depend on the steepness of the inclined plane?
Assuming you are asking about an object that is placed on an inclined plane and the only forces acting on it are gravity and friction; as the slope of the plane increases, more of gravitational force is applied down the plane and less of the frictional force is applied to the object up the plane. Unless there is no frictional force, until the plane reaches a certain critical slope the gravitational force will not overcome the frictional force and the object will not move, and the average speed for the object will be zero regardless of the slope of the plane (below this critical slope). As the slope increases there is an increase in the net force on the object down the plane which results in a higher acceleration down the plane, and with a higher acceleration it will reach a higher speed and so the average speed of the object down the plane will be higher. So, yes, it can be said that the average speed of an object down an inclined plane is dependant on the slope of the plane. If there are other forces involved, for example a motor, then the average speed will depend on these forces as well as the slope.
What is 2500 divided by 2000?
1.25
Levers explain how the force applied by a lever is affected by its distance from the fulcrum?
In a lever, the force applied is inversely proportional to the distance from the fulcrum. This means that the farther away the force is applied from the fulcrum, the less force is needed to lift the load. This relationship is governed by the principle of torque, where force is multiplied by distance.
What is the part of a lever on which the effort force is applied is called?
Fulcrum
The fix point of a lever is called a?
The fixed point of a lever is called the fulcrum. A lever is a beam connected by a hinge, or pivot, called a fulcrum. A lever is used to amplify the applied force.
What describes the distance from the applied force to the fulcrum?
The distance from the applied force to the fulcrum is called the effort arm or lever arm. It is the perpendicular distance between the line of action of the force and the fulcrum in a lever system. The length of the effort arm affects the mechanical advantage of the lever.
How is fulcrum used?
A fulcrum is a point around which a lever pivots, allowing for the applied force to be amplified or redirected. It is used in tools like seesaws, wheelbarrows, and scissors to make work easier by leveraging the force applied.
Point around which a lever rotates?
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
The fixed balance point on a lever?
The fixed balance point on a lever is called the fulcrum. It is the point at which the lever pivots or rotates when a force is applied to either side of the lever. The position of the fulcrum determines how the lever amplifies or redirects the force applied to it.
Would a 9-n force applied 2 meter from the fulcrum lift the weight?
Yes, the force applied is calculated by multiplying the force by the distance from the fulcrum. In this case, the torque applied would be 18 Nm (9 N * 2 m). Whether it is enough to lift the weight depends on the weight and the distance from the fulcrum at which it is placed.
What class lever is the fulcrum located between the input force and output force?
A class 1 lever has the fulcrum located between the input force and output force. This means that the force is applied on one side of the fulcrum and the load is on the other side, with the fulcrum acting as the pivot point in the middle.
What is between the fulcrum and input force on a lever?
The load or resistance is positioned between the fulcrum and the input force on a lever. The input force is applied on one side of the fulcrum, while the load is typically located on the opposite side. The lever uses this arrangement to magnify the force applied to move the load.
On which type of simple machine would you find a fulcrum Explain what a fulcrum is?
A fulcrum is found on a lever, which is a type of simple machine. A fulcrum is the fixed point around which the lever pivots or rotates. It helps to transfer and multiply force applied to one end of the lever to lift or move objects at the other end.
What is the term for the point on which a lever pivot?
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
