Question

The block of mass 5 kg is moving downward with an
acceleration as shown in the figure. If strings and
pulley are massless and rigid, then what will be the
tension in the string connected with 1 kg and 1.2 kg
block? [Take g = 10 m/s2]​

Answer 1

Answer:

In the system as shown in figure AB is a uniform rod of mass 10 kg and BC is a light string which is connected between wall and rod, in vertical plane. There is block of mass 15 kg connected at B with a light string.

(Take g=10 m/s

2

) (BC and BD are two different strings)

If whole of the system is in equilibrium then find

(i) Tension in the string BC

(ii) Hinge force exerted on beam at point A
