It is desired to design a system for controlling the rate of extension of the fire-truck ladder during elevation of the ladder so that the bucket B will have vertical motion only. Determine if the elongation rate of the hydraulic cylinder is 0.7 ft/sec and θ = 21°, L = 13 ft, h = 3.2 ft, b = 9 ft, and x = 5 ft.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
