The effective lever arm will be enhanced if we utilize a big diameter string.
<h3>What is Lever Arm?</h3>
The perpendicular distance from the axis of rotation to the force's line of action is specified as the lever arm.
When a big diameter string is utilized, the effect of the diameter on the string of the lever arm will be enhanced.
This is due to the reason that if the radius of the pulley is R and the radius of the string is r, then the effective lever arm becomes R+r.
If the radius,r of the string is very minute such that its addition to the radius of the pulley, R will hardly make a change to the effective lever arm, then it is avoided. However, if the radius of the string is a big number then it can not be avoided as it can make significant errors in the calculation of the effective lever arm.
Hence, The effective lever arm will be enhanced if we utilize a big diameter string.
