1. Determine the force in the hydraulic cylinder AB and the magnitude of the pin reaction at O for the position shown. The bucket and its load have a combined weight of 4000 lb with center of gravity at G. You may neglect the effect of the weights of the other members.
2. The power unit A of the tractor-scraper has a mass of 5.4 Mg with mass center at G1. The fully loaded trailer-scraper unit B has a mass of 22.7 Mg with mass center at G2. Positioning of the scraper is controlled by two hydraulic cylinders EF, one on each side of the machine.
Calculate the compression F in each of the cylinders and the magnitude of the force supported by each of the pins at H, one on each side. Assume that the wheels are free to turn so that there are no horizontal components of force under the wheels.
For plain carbon steel and convection (h=50 W/m^2 K) to air at 500K, Ti=300k, with a slab geometry 0.2 m thick (2L), find Boat Number. For a Fourier number (based on l=0.1m) of 0.1, is the tearm series valid? Find the time

The inside diameter of the bottle is equal to the inside height of the bottle. Write the equation to assess the ratio of radiation resistance over convection resistance. What is missing from numerically calculating the radiation heat transfer coeffic..
25 kg of water are placed in a rigid, initially evacuated container which has a volume of 2 m3 . After sitting for some time, the pressure stabilizes at 10.0 bars. What is the specific entropy (kJ/kg K)of the liquid vapor mixture?
Water is pumped from a reservoir to a tank with a lift of 20.0 ft. The suction pipe, which connects the reservoir to the pump, has a 12in diameter and is 25ft long. The discharge pipe, which connects the pump to the tank, has a 10in diameter and is 4..
