How is torque used in a seesaw?
How is torque used in a seesaw?
Torque is defined as force times distance, where the force acts perpendicular to the distance about a point of rotation. If the sum of the torques that cause rotation in a clockwise direction equals the sum of the torques that cause it to rotate counter clockwise, the seesaw remains balanced.
What is a torque in physics?
torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied.
Does a seesaw utilize the principles of torque?
In order for the seesaw to be balanced, the torque must be equal on each side of the pivot point. Use the equation for torque in this equation. The force of each object will be equal to the force of gravity. The total length of the seesaw is two meters, and the child sits at one end.
How do you find torque physics?
Torque is defined as Γ=r×F=rFsin(θ). In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, ‘a’ being the angle between r and F.
Can torque be equal to tension?
The force of gravity is shown in green. For method 1, the torque from the tension is calculated from the full torque equation, multiplying the tension force by the distance the force is along the rod from the hinge, multiplied by the sine of the angle between those two lines.
What are the conditions in which force Cannot produce torque?
If no force acts on a body, then the body does not start spinning. If two or more forces are put at the same point so that they cancel each other out, then also the object will not spin. If the force acts on the axis of rotation, then force cannot produce torque.
How do you balance a seesaw with torque?
This problem requires us to add torques about the pivot point. In order for the seesaw to be balanced, the torque must be equal on each side of the pivot point. Use the equation for torque in this equation. The force of each object will be equal to the force of gravity.
What is the torque due to the new mass of the see-saw?
From Sample Problem 1 we know that the torque due to the original mass is -58.8Nm. Since the sum of all torques must be zero when the see-saw is balanced, the torque due to the new mass must be +58.8Nm: The new mass should be placed 1.2m to the left of the pivot point.

How do you solve a seesaw problem?
This problem requires us to add torques about the pivot point. In order for the seesaw to be balanced, the torque must be equal on each side of the pivot point. Use the equation for torque in this equation. The force of each object will be equal to the force of gravity. Gravity can be canceled from each side of the equation. for simplicity.
Why can’t a seesaw feel gravity?
As far as the seesaw is concerned, all that matters are the forces directly on it: the two normal forces from the masses, the normal force from the fulcrum, and gravity on itself. It can’t ‘feel’ the gravity on the masses. It’s a bit confusing because you reuse symbols to mean different things. If you do that others have to guess what you mean.
