A bar having a cross-sectional area of 6 in. is subjected to an axial tensile load of 39,000 lb. Using Mohr's circle:
(a) Find the normal and shear stresses on planes with normals inclined at 75°, 65°, and 50° counterclockwise from a plane perpendicular to the longitudinal axis.
(b) Find the maximum shear stress.
A gearbox operating at steady state receives 2 hp along the input shaft and delivers 1.89 hp along the output shaft. The outer surface of the gearbox is at 110°F and has an area of 1.4 ft.2 The temperature of the surroundings away from the immediat..

If a level of service no worse than C is desired, determine the maximum number of large trucks and buses that can be present in the peak-hour traffic stream.
Water enters a reach of rectangular channel where y1 = 0.5 m, b = 7.5 m, and Q = 20 m3 /s (Fig. P10.39). It is desired that a hydraulic jump occur upstream (location 2) of the sill and on the sill critical conditions exist (location 3). Other than ..
A 1982 U.S. Department of Energy article (FS#204) states that a leak of one drip of hot water per second can cost $1.00 per month. Making reasonable assumptions about the drop size and the unit cost of energy, determine if this claim is reasonable. S..
