Question

Torque T = F (Force) x L (Length)

You are using a wrench in an attempt to loosen a nut by applying a force as shown; but this fails to loosen the nut. Which one of the following choices is most likely to loosen this tough nut? Select all that apply.

Doubling the length or doubling the force will have the same result, but doubling the length is easier.

Continue applying the same force as in the drawing and eventually the nut will loosen.

Place a pipe of length 2L over the handle of the wrench and apply the same force F to the opposite end(farthest from the nut).

Tie a rope of length 2L to the wrench at the same location and apply the same force as shown.

Double the force.

Answer 1

Page No. Anda T= fx L -> we can easily Increase the bngth by '2 L by placing a si pipe on the handle of wrench. as shown in figure e FX2L = 2Ti (By By using rope of a Ľ length we can apply k force in perpendicular rope direction as shown fer of producing the toque for rotation Total Torque T3 = FAL, Here no effect on the effective arm of torque.so it will not be useful for an increasing the torque. So we have to opt the of - And
