Rigid bar abc is supported by a pin at bracket a and by tie rod (1). tie rod (1) has a diameter of 7 mm, and it is supported by double-shear pin connections at b and d. the pin at bracket a is a single-shear connection. the pin at b is 8 mm in diameter. assume a = 540 mm, b = 270 mm, h = 340 mm, and θ= 55°. if the normal stress in tie rod (1) cannot exceed 180 mpa and the shear stress in pin b cannot exceed 130 mpa, determine the maximum load pmax that can be supported by the structure.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

How much power could a wind turbine produce if it had the following specifications? cp = 0.45 -d=1.2kg/m3 d=50m v 5m/s
