Two parts of a machine are held together by bolts, each of which carries a static tensile load of 3100 N.
(a) What size of class 5.8 coarse-thread metric bolt is required using a safety factor of 4 (based on proof strength)?
(b) What is the least number of threads that must be engaged for the thread shear strength to be equal to the bolt tensile strength if the nuts are made of steel whose yield and proof strengths are 70 percent those of the bolt steel?
Sketch the crankshaft, connecting rod, piston, and frame as free bodies when the piston is 60° before head-end dead center on the compression stroke. Sketch the entire compressor as a single free body for this condition.
Assume that 2 cfs of oil (viscosity 0.16P and specific weight of 54 lb/ft3) is pumped through a 12 inch pipeline of cast iron. If each pump produces 80 psi, how far apart can they be placed?
Derive the continuity equation from first principles using an infinitesimal control volume of rectangular shape and having dimensions (?x, ?y, ?z). Identify the net mass flow rate through each surface of this element as well as the rate at which the ..

A gas sample is known to be a mixture of ethane and butane. A bulb having a 230.0 cm3 capacity is filled with the gas to a pressure of 97.5 X 103 Pa at 23.1°C.
The tower approach is 10 F and the air outlet state is 90 F and saturated. Draw some conclusions from your analysis
Define the first order differential equations using the state variables - define a state variable model for the system in a matrix notation.
A thin-walled cylindrical pressure vessel is capped at the end and is subjected to an internal pressure (p). The inside diameter of the vessel is 6 ft and the wall thickness is 1.5 inch. The vessel is made of steel with tensile yield strength and com..
