Determine the deflection at C. Let P = 200 lb, a = 107 in., b = 29 in., and EI = 42 × 106 lb·in.2.

If the support at B has settled downward a distance of Δ = 0.05 in., determine the reaction force at B. Let w = 7 lb/in., a = 134 in., and EI = 38 × 106 lb·in.2.

Determine the deflection at C. Let w = 12 lb/in., a = 72 in., b = 30 in., and EI = 241 × 106 lb·in.2.

Determine the maximum deflection of the beam. Let w = 18 lb/in., a = 132 in. and EI = 47 × 106 lb·in.2.
