Question

The diagram alongside shows a uniform meter rule of weight 100 gf being balanced on a Knife edge llaced at the 40 cm mark by suslending a weight w gf at the mark 20 cm ,find
i. The ealue of w.
ii. The resultant moment and it’s direction if the weight w is moeed to the 30
cm mark.
iii. The losition of another weight of 50 gf to balance the rule in lart ii.

Answer 1

Answer:

When a torque is applied to an object it begins to rotate with an acceleration inversely proportional to its moment of inertia. This relation can be thought of as Newton's Second Law for rotation. The moment of inertia is the rotational mass and the torque is rotational force. Angular motion obeys Newton's First Law.
