Question 1:A bar of uniform cross section and weighing 100 N is held horizontally using two massless and inextensible strings S1 and S2 as shown in the figure.
Question 2:A force F is acting on a bent bar which is clamped at one end as shown in the figure.
The CORRECT free body diagram is
Fixed support should be replaced by vertical reaction, horizontal reaction and a moment reaction in free body diagram.
Question 3:A rigid ball of weight 100 N is suspended with the help of a string. The ball is pulled by a horizontal force F such that the string makes an angle of 30° with the vertical. The magnitude of force F(in N) is ______.
Applying Lami’s theorem
F = 57.74 N
