1. A bar AB of weight W is hinged to a vertical wall at A
and supported at B by a string BC as shown in Figure.
Find the magnitude of tensile force in the string BC.
Take α = 300
2. A 750 N man stands on the middle rung of a 250 N
ladder, as shown in figure. Assuming the end B rest on
the corner of a wall and a stop at A to prevent slipping,
determine the reaction at A and B.
3. A right angled bar is supported by roller at B and a
hinge at A, as shown in Figure. Find the reaction at A
and B due to a load P applied as shown.
4. A roller of radius 100 mm and weight 200 N is to be
publled over a curb of height 40 mm by a force P
applied at the center O, as shown in Figure. Find the
minimum force P required to start the roller over the
As figure is not given in this so i am assuming figure for this question
In equilibrium condition we know that
on solving we get
T= 19.84 kN
