Three boards, each 2 in, thick, are nailed together to form a 6 ft long beam that is subjected to a uniform distributed load. knowing that the allowable shearing force in each nail is 150 lb and that the spacing s between the nails is 5 in, determine the maximum allowable distributed load.

What precautions should you take to prevent injuries when dealing with heavy loads?

Steam enters a turbine at steady state at 2 mpa, 360°c with a velocity of 100 m/s. saturated vapor exits at 0.1 mpa and a velocity of 50 m/s. the elevation of the inlet is 3 m higher than at the exit. the mass flow rate of the steam is 15 kg/s, and the power developed is 7 mw. let g 9.81 m/s^2. determine: a)-the area at the inlet, in m^2 b)-the rate of heat transfer between the turbine and surroundings, in kw c)-draw a p-v diagram for this process.
