1.The beam shown has a mass of 120 kg. Determine the reactions at pinned support A and smooth surface B.
2. The lever ABC is loaded and supported. Determine the force exerted on the lever by link CD, and determine the reactions at pinned support A.
3. The man has a mass of 75 kg, and the beam has a mass of 40 kg. The beam is in equilibrium with the man standing at the end and pulling on the cable. Determine the force exerted on the cable by the man and the reactions at pinned support C.
4. A frame is supported and loaded. Determine the reactions at pinned support A and rollersupport E. (Hint: Use a FBD of the frame as one whole body.)
A solid steel sphere with a specific gravity of 7.85 and diameter of 0.02 m is falling at its terminal velocity through water at 25 °C. Using either trial-and-error or a graphical approach, determine the velocity of the sphere
A rectangular concrete channel is 3 m wide and 2 m high. The water 20 deg Celsius in the main channel is 1.5 m deep and is flowing at a rate of 30 m^3/s. determine the flow area, wetted perimeter, and hydraulic radius. is the flow laminar or turbu..
What are the basic differences between the AFL as a labor union and the CIO type of union?
A 2000-lb wheel load is to be supported by aggregate over soil with a maximum bearing pressure of 1000 lb/sqft. What depth of aggregate is needed if the angle theta is 40 degrees
To prevent this high compression load from buckling the copper pipe, a solid steel support of 2 1/2 inch diameter is placed inside the copper pipe. The copper pipe is 8.000 inches long. The steel support is 8.0001 inches (exactly 1 mil = 1/1000 in..
An elbow, 90 degrees smooth bend flanged, is used in the Alaskan pipeline. Inside pipe diameter is 48 inches. Flow is 1.6 million barrels a day. 1 barrel=42 gal. Velocity is 8.27 ft/s. SG=0.93

A tray rests on an extendible arm consisting of two steel tubes with two different outer diameters. The downward force at the tray center F0 = 1000 N. Determine the downward deflection of the tray center and the tilt angles of the tray about each ..
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
Find the discharge flowing over a rectangular sharp crested wire, in GPM, which has a width of 9.9 feet and a discharge coefficient of 3.24, if the head above the crest is 1.74 feet.
A constant power of 1.5 hp is supplied to the motor while it operates with an efficiency of ε = 0.8. Determine the velocity of the 200-lb crate in 15 seconds, starting from rest. Neglect friction.
A scale for rapidly weighing ingredients in a commercial bakery operation is shown. An empty bowl is first placed on the scale. Electrical contact is made at point A, which illuminates a light indicating the bowl's contents are underweight.
