Question

in order to tighten a nut with a spanner,a torque of 1000Nm is required.the length of spanner is 0.15m how much force needed to produce the required amount of torque?​

Answer 1

Answer:

Explanation:

FIRST CHANGE CM INTO M

Distance = 10cm = 10/100 = 1/10 m

Force applied on spanner 5 N. Moment of force = F xL distance = 5 x 1/10 = 0.5 nm.

Answer 2

☞ Answer

(1) Moment of force means torque.

τ=force×⊥distance

τ=20×0.5

τ=10N−m

(2) τ=force×distance

τ=5×10/100

=> τ=0.5N−m
