The beam shown in the figure is simply supported at A and B. The loads consist of a couple M o = 4 kN . m at A and a concentrated load P = 9 kN at the end of the overhang. Determine the shear force V and bending moment M at a section 2 m from the left-hand support.
Determine the force in each member of the loaded truss. The forces are positive if in tension and negative if in compression. Discuss the effects of varying the angle of the 52 degree support surface at C.
Cartesian system of coordinates, centered in London, with New York in the negative x direction. At the altitude the airplane flies there is a wind, blowing horizontally from north to south (negative y direction) at a speed of 100 km/h.What must be..
Fifteen kilogram of polychloroprene is vulcanized with 5.2 kg sulfur. What fraction of the possible crosslink sites is bonded to sulfur crosslinks, assuming that, on the average, 5.5 sulfur atoms participate in each crosslink?
Saturated water vapor at 100 kPa enters a counter flow heat exchanger operating at steady state and exits at 20C with a negligible change in pressure. Ambient air at 275 K, 1 atm enters in a separate stream and exits at 290 K, 1 atm.
What is the heat loss per unit length of pipe? Consider the effect of insulating the pipe with a rigid urethane foam (k = 0.026 W/m · K). Evaluate and plot the heat loss as a function of the thickness 8 of the insulation layer for 0 8 50 mm.
For the multiple-leaf spring described in Problem 12.5 (Fig. 12.17), derive the assembled stiffness and mass matrices. Consider only one-half of the spring for modeling using five beam elements of equal length.
a bonding operation utilizes a laser to provide a constant heat flux q0 across the top surface of a thin

After the collision, puckA has a velocity of 0.12 m/s to the left (-x-direction),and puck B has a velocity of 0.65 m/s to the right (+x-direction). What was the speed of the puck A before the collision?
A company is trying to decide which machine to purchase based on the following information. If they all have 15 years useful life and MARR is 10%, use incremental rate of return analysis in Excel to decide which one is the best choice. Don't forge..
A shaft with a 2-inch outer diameter must deliver 5000 ft-lbs of torque. The shaft must be hollow and must simultaneously carry hydraulic fluid at an internal pressure of 30,000 psi. Assuming the shaft is closed-ended, and using the von Mises yield c..
