The overhanging beam is made of wood with an allowable tensile stress of σtension = 4MP a and an allowable compression stress of σcompression = −5MP a. The beam is supported by a pin at A and a roller at B.

Determine the maximum force Pmax that can be applied at the end. Hint: Calculate reaction forces in terms of P.

Calculate the shear and moment diagrams in terms of P.

Find the maximum/minimum moments in terms of P.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?

What are the major differences between injection molding and extrusion?
