The block A has a mass of M and the cylinder B has a mass of m. The masses of the pulleys and the rope can be neglected. The slope angle is 20o.
The cylinder B is released from rest. Determine the speed of both masses (vA and vB) after B moves by h m. Also calculate the angular displacement for the pulley D. The diameter of the pulley D is 0.2 m. Neglect all friction.
Determine the maximum and minimum stress intensities in the section.
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.

At the end of 15 years, the first motor will have a salvage value of $50 and the second motor will have a salvage value of $100. consider the MARR to be 8%. (note : 1HP=0.7457 kw). Determine which motor should be installed based on the PW criterio..
a spherical balloon is being inflated so that its volume is increasing at the rate of 5 cu meter/min. at what rate is the diameter increasing when the diameter is 12m?
What must be the radius of the steel wire if it is to stretch the same distance as the aluminium wire, so that the two wires maintain equal lengths after the masses are attached?
This weir is to be replaced by an uncontracted horizontal weir that will maintain the same upstream depth. Determine the height of the weir if the discharge coefficient is based on the following equation: C = 1.78 * 0.22(H/p)
