Torque

A state of equilibrium is also seen below. Each of the cars weighs the same 9800 N. Despite the fact that there is only one car on the left-hand side that is 9 m from the fulcrum, the torques balance because, the cars on the right-hand side, are ____meters from the fulcrum.

A seesaw with mass x is perfectly balanced with a fulcrum in the center. If mass x changes uniformly does the net torque change?

• Yes, because the Gravitational force increases with more mass, and torque is related to Force

• No, because the net torque is still zero despite increases in one of the individual components.

• No, because it is balanced that means net torque is zero, a uniform increase in weight keeps it balanced keeping net torque at zero

• Yes, any increase in weight will increase torque

A construction worker is worried about applying too much torque to a bolt using his wrench.  What could he do to reduce his torque on the bolt?

• Increase the length of the wrench

• Increase the force on wrench

• Reduce the length of the wrench

• Reduce the friction between the bolt and wrench
