Question

The torque exerted by a crowbar on an object increases with increased _______.

Answer 1

Answer:

force and leverage distance

Explanation:

the formula for torque if = force x distance

(the distance above is the leverage distance on the crow bar)

therefore if there is an increase in either the torque or the leverage distance, or both, the torque exerted by the crow bar also increases.

for example

• lets assume a force of 5 n is applied on the crow bar with a leverage distance of 2 m.

        the torque = 5 x 2 = 10 N.m

• but if the force was increased to 7 N

        torque = 7 x 2 = 12 N.m

from the illustration above, we can see that the torque increased with an increase in force. There would also be an increase in torque if the distance were to be increased.
