(c) Torque = Force Hence for a given applied force, torque or true tendency of rotation will be high for large value of |
perpendicular distance of line of action of force from the axis of rotation (d)
. If distance 
is smaller, then greater force is required to cause the same torque, hence it is harder to open or shut down the door by applying a force near the hingeNext Question :

Statement1: |
A uniform thin rod of length |
|
Statement2: |
Under the conditions given in Statement 1 as |
|
a) |
Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1 |
|
b) |
Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1 |
|
c) |
Statement 1 is True, Statement 2 is False |
|
d) |
Statement 1 is False, Statement 2 is True |
is hinged about one of its ends and is free to rotate about the hinge without friction. Neglect the effect of gravity. A force 
is applied at a distance 
from hinge on the rod such that the force is always perpendicular to the rod. As value of 
is increased from zero to 
, the component of reaction by the hinge on the rod perpendicular to the length of rod increases
is increased from zero to 
, the angular acceleration of the rod increasesView Topper Answer
