Q1. Two men are trying to roll the boulder by applying the forces shown. Determine the magnitude and direction of the force that is equivalent to the two applied forces using both the parallelogram and the component methods Fig (11 Fig Q2 Q2. Determine P and 6' so that the three forces shown are equivalent to the single force R = 85i + Zj kN. Q3. The force R is the resultant of the forces P1r P2. and Pa acting on the rectangular plate. Find P1 and P2ifR =40 kN and 133:2!) kN. R a, .10" P1 J Fig (13 P: Fig Q4 Q4. The man exerts a force F of magnitude 25!] N on the handles of the wheelbarrow. Knowing that the resultant of the forces P. Q [the reaction at the wheel I. and W l[the weight of the wheelbarrow] is the force R = 50 i N. determine in. Q5. Find the magnitude and sense of the moment of the BODN force about points A and B
