Answer 1

Well, i think there are more than one answers for this question. What influence whether or not bricks slide down the bed of the dump trucks will depends on : 
- The mass of the Bricks
- The angle of the Bed
- The coefficient of static friction between the bricks and the bed
- the coefficient of kinetic friction between the bricks and the bed

hope this helps
