Question

a uniform beam of 200N is supported horizontally.if the breaking tension of the rope is 400N how far can block B of weight 400N from point A on the beam?

Answer 1

Explanation:

Considering the beam supported by a pivot at A and the rope at B. In that case the beam applies a load of 100 N on the rope. This means the man can walk out until he applies a load of 300 N on the rope end. At that point the rope would break. 300 N is 3/4 of 400 N so he can walk 3/4 of the way from A to B.

Answer 2

Answer:

4 A uniform beam of 200 N is supported horizontally as shown in fig.2.27 (a). If the breaking tension of the rope is 400 N, how far can a man of weight 400 N walk from A to B on the beam.
