Answer:
The moment arm is 0.6 m
Explanation:
Given that,
First force
Second force
Distance r = 0.2 m
We need to calculate the moment arm
Using formula of torque
So, Here,
We know that,
The torque is the product of the force and distance.
Put the value of torque in the equation
Where, =First force
=First force
=Second force
= distance
Put the value into the formula
Hence, The moment arm is 0.6 m
