1
Attempt any FOUR questions (5x4 = 20)
Question 1: If the resultant force of FA and FB is horizontally orientated along the
positive x-axis; determine
1. The angle θ for the connecting member A to the plate.
2. The magnitude of the resultant force?
2
Question 2: A 200-kg cylinder is hung by means of two cables AB and AC, which are
attached to the top of a vertical wall. A horizontal force P perpendicular to the wall
holds the cylinder in the position shown. Determine the magnitude A of P and the
tension in each cable.
3
Question 3: three cables are joined at the junction ring C. Determine the tensions in
cables AC and BC caused by the weight of the 30 kg cylinder.
4
Question 4: Compute the x and y components of each of the four forces shown in
figure 1. Also calculate the resultant force and it’s angle from positive x axis.
5
Question 5: Determine the magnitude of F projects components acting along the x
axis and a long cable AC. F has a magnitude of 55 Ib.
6
Question 6: Determine the magnitude P of the vertical force required to lift the
wheelbarrow free of the ground at point B. the combined weight of the wheelbarrow
and load is 240 lb with center of gravity at G.
