What is the distance between the pivot point and the marking point of a compass when drawing a circle called?
The radius
How do you calculate area wiped by windscreen wiper?
Measure pivot point to bottom of blade and pivot point to blade tip, measure angle from extreme left to extreme right of pivot point in degrees. If not possible measure the distance from top left point of blade on windscreen to top right point on windscreen.Transfer measurements to large piece of paper and draw a fan shape to represent the readings taken. Large circle area is pivot to blade tip, squared x 3.142 small circle area is pivot to blade bottom ,squared x3.142 Subtract small circle area from large circle area. This is a full 360 degree blade sweep area. Now take 360 degrees and divide by the angle of sweep, for example if sweep angle is 60 degrees:- 360/60 = 6 Divide answer by 6 to get area cleaned by wiper. Multiply by 2 for both blades in this example.
How do you balance a seesaw?
Simple ..put equal weight at each end, equal distance from the pivot.
What factors affect the period of a pendulum?
In a simple pendulum, with its entire mass concentrated at the end of a string, the period depends on the distance of the mass from the pivot point. A physical pendulum's period is affected by the distance of the centre-of-gravity of the pendulum arm to the pivot point, its mass and its moment of inertia about the pivot point. In real life the pendulum period can also be affected by air resistance, temperature changes etc.
What is a bar that is free to pivot about a fixed point?
lever.
What is the distance between the pivot point and marking point of a compass when drawing a circle?
The distance between the pivot point and the marking point of a compass is the radius of the circle being drawn.
What is the distance between the pivot point and the marking point of a compass when drawing a circle called?
The radius
The distance between the pivot point and the marking point of a compass when drawing a circle?
Well, honey, that distance is what we call the radius of the circle. It's the measurement from the center point (the pivot) to the outer edge (the marking point) where all the magic happens. So, grab that compass, find your center, and strut your stuff drawing those circles like a pro!
Rotates in a circle?
pivot joint
What is the magnitude of the torque about the pivot point?
The magnitude of the torque about a pivot point is given by the product of the force applied and the distance from the pivot point to the line of action of the force, multiplied by the sine of the angle between the force and the lever arm. Mathematically, torque = force * distance * sin(angle).
How do you work out the amount of force on a pivot?
To calculate the amount of force on a pivot, you would use the equation: force = distance from pivot x weight. The weight is the downward force acting on the pivot, and the distance is the distance from the pivot point where the force is applied. By multiplying these values together, you can determine the amount of force on the pivot.
How can the IMA of a first- class lever be increased Decrease the length between the applied effort and the pivot. Increase the length between the applied effort and the pivot. Decrease the applied ef?
The IMA of a first-class lever can be increased by increasing the distance between the applied effort and the pivot point. This creates a longer lever arm, allowing for more torque to be produced with the same amount of force. Alternatively, decreasing the distance between the load and the pivot can also increase the IMA by reducing the effort required to lift the load.
How does the moment of a force depend on distance from the pivot?
The moment of a force (torque) is directly proportional to the distance from the pivot point. The moment increases as the distance from the pivot point increases, and decreases as the distance decreases. This relationship is described by the equation: moment = force × distance.
What is the pivot point on a counter balance forklift when turning?
The front wheel on the inside of the turning circle is the pivot point.
What are the 3 ways you can change torque?
You can change torque by adjusting the force applied, changing the distance between the force and the pivot point, or altering the angle at which the force is applied relative to the pivot point.
What would increase the mechanical advantage of a second class lever?
Increasing the distance between the pivot point and the effort force, or decreasing the distance between the pivot point and the load, could increase the mechanical advantage of a second-class lever. Additionally, using a longer lever arm can also increase the mechanical advantage.
Why torque is zero when force is applied to point that passes through pivot point?
When a force is applied at a point that passes through the pivot point, the lever arm (the perpendicular distance between the pivot point and the point of force application) is zero. Since torque is defined as force multiplied by the lever arm, when the lever arm is zero, the torque is also zero. This means that the force does not create a rotational motion around the pivot point.
