A hydraulic crane of total mass (including the mass of the boom) 5300kg supports a load of 800kg. The boom mass 500kg is 7m long and makes an angle of 50 degrees with the horizontal. The boom's center of the boom length. Also assume that the center of mass of the crane excluding the boom acts at the middle of the outrigger jacks that are 4m apart. Draw the FBD of the crane and boom. Find the reaction force at the rear outrigger jack (Nr) and at the front (Nf) for the system to be in equilibrium. Assume the ground is friction less.

1. A car is able to provide 300kW of tractive power, as it accelerates from 36 to 288km/hr, along a flat and level section of road. This is achieved in 2 seconds. a) Calculate the tractive force at 36km/hr.
Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
While winching a Jeep straight out of the mud, a winch uses 4800Watts of electrical power to pull the 1500-kg Jeep 12meters as it accelerates at 0.15. This takes a the winch 20 seconds to accomplish. Calculate... a.) the force of tension in the cable for the winch to pull the jeep. b.) the work done by the winch to pull the jeep. c.) the power done by the winch to pull the jeep. d.) the efficiency of the winch in this scenario.
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…
