1.In grain size distribution of sieve analysis, what is the significance of the #4 for sieve #4? Where does this come from and whats the logic behind it? For example #4, #10, #20, #40, #60...etc what is the significance of this number?
2.Draw the influence line for the tension in cable BC. Neglect the thickness of the beam, What is the maximum tension in the cable due to the 6-k loading?
3.Where should a single 500-lb live load be places on the beam so it causes the largest live moment at D? What is this moment? Assume the support at A is fixed, B is pinned, and C is a Roller
