1. Hydraulic jacks are one of the many tools humans use to develop a so-called "mechanical advantage". The basic idea is that a relatively small force applied to the smaller-area piston can counteract a relatively large force applied to the larger-area piston. F₂ a) Ignoring the weight of the fluid (i.e., ignoring changes in hydrostatic pressure due to the density of the fluid) and any friction between the piston and the sidewalls, show that F2 = F₁ AR A₁ in static equilibrium. b) The mechanical advantage of the hydraulic jack can be defined as the ratio of the force applied to piston 2 to the force applied to piston 1 in order to keep the system in static equilibrium. For circular pistons, use the relationship in part a) to plot the mechanical advantage as a function of the diameter ratio of the pistons. Explain the significance of this mechanical advantage. c) Consider a hydraulic jack in static equilibrium with both pistons at the same elevation. If you do not consider the weight of…

Rank the mass of an object under the following circumstances. If masses are equal sostate. Object cold and at rest in a refrigerator Object hot and at rest in an oven Object cold and in motion in orbit Object hot and in motion in orbit

With the blocks initially at rest, the force P is increased slowly from zero to 134 lb. Plot the accelerations of both masses as functions of P. Then answer the questions. ₁0.40] Ha=0.35 = 0.35) B Ha=0.30 Questions: A 78 lb 102 lb If P = 49 lb, dA= If P=111 lb, A= If P= 131 lb, A= i ft/sec² 08= ft/sec² ag ft/sec² ag i ft/sec² ft/sec² ft/sec²
