1.Given simply supported beam with an overhang. The beam is 12 inches wide by 24 inches deep, and the slab is 6 inches deep. use a roof live load of 20 psf, and a concrete density of 150 pdf. the beams are spaced 15 feet apart. the total beam length is 30 feet, with 24 feet between supports and a 6 foot overhang. plot the shear and moment diagrams for the beam.
2.Determine the gravitational force acting between two spheres that are touching each other. The mass of each sphere is 400 kg and the radius is 300mm.
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 of 6..

A catheter is a specialised needle intended for long-term insertion into a vein in a patient's arm. Engineers are redesigning them to cause less discomfort and damage. An intravenous chemotherapy system is based on a new catheter design. A liquid dru..
Saturated liquid water is in an adiabatic compressor with inlet and outlet pressures of 100 kPa and 1 Mpa. The isentropic efficiency is 85%. Find the work input (kj/kg) and entropy generation (kj/ kg K).Do the same for saturated vapor steam in an adi..
The emission rate of radon into the crawl space is reported to be 0.6 pCi/m^2-s. An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space. The outdoor concentration of radon is 1 pCi/L.
A package is at rest on a conveyor belt which is initially at rest The belt is started and moves to the right for 1.3s with a constant 'a' and comes to a stop after a total displacement of 2.2m.
A company produces two kinds of septic tanks: type A and type B. Each type B tank takes twice as long to produce as a type A tank. If it only produced type A tanks, the company has the time to produce a maximum of 2000 tanks per week.
