Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of = 74.0 with the floor and rope segment CD creates an angle with the horizontal. If both ropes BCA and CD can support a maximum tensile force = 625 , what is the maximum weight of the crate that the system can support? What is the angle required for equilibrium?
a bourdon pressure gauge attached to the outside of a tank containing air reads 77.0 psi when the local atmospheric pressure is 760 mm Hg. what will be the gage reading if the atmospheric pressure increases to 773 mm Hg

Calculate the largest tolerable internal crack length for a 7075-T651 aluminum alloy component that is loaded to a stress one-half of its yield strength without catastrophic fracture.
a storage tank has a diameter of 80 ft, a height of 25ft and contains oil to a height of 15ft. the suction pumps, which can handle 15000bbl/d, are started, but the safety valves are clogged and a vacuum is drawn in the tank.
Determine the air pressure at the top of a 300 m high building by assuming the density of air stays constant at the z = 0 value. Now compute the pressure assuming the density of the air varies. Is there a significant difference.
An aluminum alloy rod has a circular cross section with a diameter of 8 millimeters. This rod is subjected to a tensile load of 4 kN. Assume E=69 GPa. What will be the lateral strain if Poisson's ratio is 0.33
A cylinder fitted with a frictionless piston contains 2 kg of superheated refrigerant R-134a vapor at 350 kPa, 100oC. The cylinder is now cooled so that the R-134a remains at constant pressure un- til it reaches a quality of 75%.
A chemical plant uses a tube-within-a-tube counterflow heat exchanger to heat air with the use of steam. During steady state operation, the air flows into the exchanger at a rate of 5,000 kg/h and a temperature of 27C and exits at a temperature..
