The length of a bicycle pedal arm is 0.152 m, and a downward force of 118 N is applied to the pedal by the rider's foot. What is

Veseljchak [2.6K]

Answer:8.968 N-m

Explanation:

Given

Length of arm=0.152 m

Downward force=118 N

angle made by arm with vertical $=30^{\circ}$

Force can be divided into two components

It's sin component will contribute towards torque while cos component will not contibute

$Torque =Fsin30\times L$

$T=118\times sin30\times 0.152$

T=8.968 N-m
