Question

A 20 cm wide thin circular disc of mass 200g is suspended to a rigid support from a thin metallic string. by holding a rim of disc,the string is twisted through 60° and released. it now performs angular oscillation of period 1 second calculate the maximum restoring torque genrated in the string under undamped condition(π^3= 31).​

Answer 1

Answer:

0.421 N-m

Explanation:

1) Find the length from time period.

2) Then use ' Torque= (-) Lmgsin(theta) ' { Negative sign shows direction}
