A collar with a mass of m can slide along a smooth (frictionless) shaft with angle α measured from horizontal direction. The collar is attached to a light spring with stiffness k and unstarched length a. The other end of spring is attached to a fixed point). The collar starts from rest in A when it is pulled by a force P which is constant. P is at an angle β measured from the shaft. β is constant as well. Find the speed vB of the collar in the time instant it is at point B. (Given Parameters: m, a, b , k, P, α, and β)

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
