A pulley-load system is used to open and close the gate AB as shown. The gate is 5 m long and 2.5 m wide and has a mass of 4.7 tons. The load is a cube made of concrete with density of 2400 kg/m. a) Determine the minimum volume of the cubic load that is required to hold the gate in this closed position. b) Suggest a simple modification that can be done in the system in order to further reduce the minimum volume of the cubic load required for keeping the gate in closed position.

A lever with a mechanical advantage of 6 is attached to the pump piston of a hydraulic press. The area of the pump piston is 1.2 in2 and that of the output piston is 18 in2. If press is 75% efficient, a 2700 lbs force the output piston exerts when a force of 30 lbs is applied to the pump lever. A.) If each stroke of the lever moves the pump piston 1 inch, how many strokes are needed to move the output piston 8 inches?

A Midwest Cooperative needs to store 15 750 gallons of a liquid chemical. They are considering two possible containers, a hollow cylinder or a hollow sphere. The wall of the sphere will need to be 6 in. thick and the wall, top and bottom of the cylinder are each 6 in. thick. Due to space limitations the height of the cylinder must be 26.0 ft. (a)What will be the outside diameter of the cylinder required to hold the liquid chemical? (b)What will be the outside diameter of the sphere? (c)Assume the containers are made of aluminum, which container uses the most material?
