Question

(a) Calculate the magnitude of the tension in the wire.
1          N

(b) Calculate the magnitude of the horizontal and vertical components of the force that the wall exerts on the left end of the beam. Fx = 2 N Fy = 3 Fx = 2 N Fy = 3

Explanation / Answer

for horizontal equilibrium of rod;=> N cos 50 = Fx cos 30; ; ; for vertical equilibrium of rod;=> N sin 50 + Fy = 1960 + 1330; ; ; For rotational equilibrium of rod about the hinge point;=> 1330 *l/2 cos 30 + 1960 *l* cos 30 = N sin 50 *l; ; ; ; from the above three equations; N = 2967.61 N , Fx = 2202.64 N , Fy = 1016.68 N
