A 2-kg block slides on the smooth circular path (Quadrant One of full circle, block moving left to right). If it is released from rest when theta=0 degrees, determine the force it exerts on the path when it arrives at Point A (Located theta=30 degrees measured from vertical axis. Radius of quarter circle: R=2m
a) Solve using F=ma (vertical)
b) Solve using CME (Work-Energy)
The motor A delivers 3000 hp to the shaft at 1500 rev/min, of which 1000 hpis removed by gear B and 2000 hp is removed by gear C. Determine
Write a detailed set of instructions (algorithm) for replacing the tire and inner tube on the front wheel of a ten-speed bicycle. The bicycle has caliper brakes that must be loosened unless the tire is not inflated.
A closed storage building is located on open flat terrain in central ohio. If the side wall of the building is 20ft high, determine the external wind pressure acting on the windward and leeward walls. Each wall is 60ft long.
The bar AB has an axial rigidity of EA. The bar is rigidly attached at A while there is a gap at B. A load P acts at point C and has a large enough magnitude to close the gap at B.
Use the Rankine cycle. The boiler operates at a 1000 kpa with a maximum temperature of 30 degrees Celsius. The condenser is isobaric and operates at -5 degrees Celsius.
Investigate the possibility of environmental problems that faced by the area of disaster.

Maintenance expenses for a bridge in Georgia are estimated to be $200,000 for the first eight years followed by two separate million dollar expenditures in years 12 and 18. The expected life of the bridge is thirty years.
At a point in a saturated normally consolidated clay layer the soil is subject to an in-situ vertical effective stress of 50kPa. The soil at the point has a moisture content of 44% and a compression index of 0.45. The effective stress at the point is..
A manometer is used to measure the pressure difference between points A and B in a pipe. Water flows in the pipe, and the specific gravity of the manometer fluid is 2.8. The distances and manometer deflection are indicated.
