Question

A uniform rod with weight 40N rest on two supports p and q and three weights are suspended . calculate the reaction on x and y​

Answer 1

Answer:

hope it helps uu

Explanation:

Since the system is in equilibrium;

The moment of forces about point A should be zero.

Thus;

10g×0.5+15g×1=Tsin53o×150+150=0.8TT=250 N

At point A, the hinge force is working which can be resolved as Ry & Rx

Rx=Tcos 53oRx=250×0.6=150 NRy=Tsin53oRy=250×0.8=200 N

R=(Rx)2+(Ry)2R=1502+2002R=250 N

Therefore, The tension in the string will be 250 N and the hinged force at point A will be 250 N
