Question 5 The beam is subjected to the distributed loading. Determine the length b of the uniform load and its position a on the beam such that the resultant force and couple moment acting on the beam are zero. Where: w1=600 N/m w2= 900 N/m a= 3m c= 3m d= 1.8m

Question 6 While empting a wheelbarrow, a gardener exerts on each handle AB a force P directed along line CD. Knowing that P must have a 135N horizontal component, determine a) the magnitude of the force P b) its vertical component

Question 7 If Θ= 45°. determine the moment produced by the 4-kN force about point A.

Question 8 The member is subjected to a force of F=6kN. If Θ= 45°. determine the moment produced by F about point A.

Question 9 In order to raise the lamp post from the position shown, force F is applied to the cable. If F =1000N, determine the moment produced by F about point A.

Question 10 The wooden plank resting between the buildings deflects slightly when it supports the 50-kg boy. This deflection causes a triangular distribution of load at its ends, having maximum intensities of WA and WB . Determine WA and WB , each measured in N/m , when the boy is standing 3 m from one end as shown. Neglect the mass of the plank.

Question 11 Determine the distance d for placement of the load P for equilibrium of the smooth bar in the position θ as shown. Neglect the weight of the bar.

Question 12 Determine the reactions at the roller A and pin B
