1.A rectangular tube has an outside dimensions that are 2in wide and 4in deep and a wall thickness of 0.25in. The tube is acted on by a bending moment of 12,000lb-in. A.)Determine the maximum tensile and compressive bending stresses.
B.) the bending stress 0.25in from the bottom of the tube
2.The 2kg block A and the 5kg block B are initially at rest on the inclined plane at 20 degrees. All surfaces in this system have a coefficient of static friction of 0.6 , and a coefficient of kinetic friction of 0.4 . Calculate the size of the mass ‘m’ so that block A slides relative to block B. block m is suspended over the wedge via pulley attached to B. A is at rest on top of block B
If A cross product B = the vector C, calculate the angle "a" between the vectors A and C and between the angle "b" between the vectors B and C.
A composite beam is made by attaching the timber and steel portions with bolts of 14-mm diameter spaced logitudinally every 200 mm. The modulous of elasticity is 10 GPa for the wood and 180 GPa for the steel.
A 3-point bending test is performed on a 10 mm diameter rod of Silicon Carbide. The distance between the supports is one foot. If the load at fracture is 10,000N, what is the flexural strength of the rod
A meat packing plant manager is trying to decide between twodifferent methods for cooling cooked hams. the spray methodinvolves spraying water over the hams until the ham temperature isreduced to 30 degrees Celcius. With this method approximately 80l..
Suppose that a water treatment plant has a Parshall Flume with a 4 ft wide throat. a) If the upstream depth of the water (ha) is 1 ft and the depth of the water in the throat section (hb) is 0.65 ft, what is the flow rate in gpm
Consider the design of wastewater treatment plant for a community wiyh average daily and peak hourly wastewater design flows of 2.0 mgd. The raw sewage has an average of 230 mg/l BOD5 and 260 mg/l of suspended solids.
Two identical uniform boards, each of weight 40lb, are temporarily leaned against each other. Knowing that the coefficient of static friction between all surfaces is 0.40
For a car traveling 35 mph the distance required to brake for a stop is normally distributed with mean of 55 feet and standar deviation of 8 feet. You are traveling 35 mph in a residential area and a car moves abrupt into your path at a distance o..
