Question

JL e probiehs. Also identify all constants and adseu lih your calculations. Clearly identify your answers by underlining them. For all proplems the following properties can be used; γ(H20)-62.4 lbs/ft3 (9.81 kN/m3) pts) Problem 2. A solid brass sphere (see figure below) of 30-cm diameter is used to weight down a cylindrical buoy in sea water (sp. gr. -1.03). The buoy has a total height of 2 m and here at one end. What rise in tide, h, will be required to lift the anchor off the bottom? 2. 50 cm 0 cm Friz= 37.48 KN sp . gr. = 13.5

Answer 1

Force B_down: - Sigma f_y = 0 f_B outforce = w_way + w_ball = (p g v)_B say + (p g v)_ball 0.06437 (2-h) = 0.05625 + 0.06075 (2-h) = (1.8176) h = 0.1823 = 18.238 height = 18.25
