Q1. Determine all of the forces acting on member ABE of the frame shown below.
Q2. Draw the shear and bending moment diagrams for the loaded beam shown below. For full credit, you must determine and note the minimum and maximum shear and bending moment values on your diagrams, respectively.
Q3. A 20 lb piece of equipment is placed on a wooden skid that weighs 10 lb and that rests on a concrete floor as shown below. Assume a coefficient of static friction of 0.45 and determine the minimum pushing force P along the handle necessary to cause the skid to start sliding across the floor.
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
Given that the max shear strength of the the concrete shore is 10 kPa and the engineer requires a F.S. of 2.5, find the required are of concrete for the thrust block.
The flat circular disk rotates about a vertical axis through O with a slowly increasing angular velocity ?. Prior to rotation, each of the 0.60-kg sliding blocks has the position x = 29 mm with no force in its attached spring. Each spring has a stiff..
A horizontal curve on a two-lane highway is designed with a degree of curvature of 7 degree and a 50mph design speed. The coefficient of side friction for the design speed is 0.14. Deflection angle is 90 degree.
a bearing wall carries a dead load of 120kn/m and live load of 100 kn/m. It is to be supported on a 400mm deep continuous footing underlain by a medium sand (unit weight = 19.2 kn/m3, phi= 37 deg, effective c = 0).
A proposal has been submitted to replace a group of assembly workers, each working individually, with an assembly line. The following table gives the individual work elements. The demand rate for this job is 1600 units/week (assume 40h/week)
The uniform 25 kg plate is welded to the vertical shaft, which is supported by bearings A and B. Calculate the magnitude of the force supported by bearing B during application of the (M =) 140 N·m couple to the shaft.
Draw the shear and moment Diagram for a beam that is 10 feet long, supported on the left end by a roler, and the right end by a pin, and has a 1000 lb load placed in the center i.e at 5 feet.
a concrete cylinder having a diameter of 6 in and a gauge length of 12 in is tested in compression the results of the test are reported in the table as load vs contraction. Draw the stress strain diagram using scales of 1 in=.5ksi
A hydraulic jump is observed to occur in a channel with a mild slope at a flow rate of 20cfs/ft. If the depth before the jump is 1 ft, determine the depth after the jump.
Compare the relative contributions of a treated water supply and the collection, treatment and disposal of human wastes towards the control of epidemic diseases in developing countries. If there are insufficient resources for both systems, should one..
Estimate the chronic daily intake of 1,1,1-trichloro ethane from exposure to a city water supply that contains a 1,1,1-trichloroethane concentration equal to the drinking water standard of 0.2 mg/L.
