Question

A circular roller of weight 1000 N and radius 20 cm hangs by a tie rod AB = 40 cm and rests against a smooth vertical wall at C as shown in figure. Determine the tension in the rod and reaction at point C. Hint: Tie rod means rod subjected to tensile force as cable. ​

Answer 1

Answer:

Solution. Let us draw the free-body diagram of the circular roller.

Sin θ =20/40 =1/2  ; θ = 300  

Applying conditions of equilibrium

Ʃ f x = 0

-f sin θ + R c =0

Ʃ f y = 0 => f cos θ -1000  = 0

From (2)          f = 1000 /cos 300  = 1154 .7 N

From (1)          RC =F sin 300  = 1154.7 sin 300 =577.35 N
