A 60 N weight is Supported by a cable attached to an end of a light rod, whose other end is hinged at point P. The rod is supported by a second cable as shown. The force exerted by the hinge on the rod has magnitude.
Text Solution
Verified by ExpertsThe correct answer is:
A
Suppose N is the normal induced in the rod, then it is also equal to force exerted by the hinge on the rod. For horizontal equilibrium
T cos 45 0 = N cos 45 0 ⇒ ⇒ T = N
For vertical equilibrium
2N cos 45 0 = 60
⇒ ⇒ N = 42N
