During a brake test, the rear-engine car is stopped from an initial speed of 100 km/h in a distance of 50 m. If it is known that all four wheels contribute equally to the braking force, determine the braking force F at each wheel. Assume a constant deceleration for the 1500-kg car.
The rod is made of a-36 steel and has a diameter of .25 in. if the springs are compressed 0.5 in when the temperature of the rod is T=40F, determine the force in the rod when its temperature is T=160 F. K=1000lb/in. and length is 4 ft long.
Air enters the compressor at 98 kPa and 295 K at a rate of 10 kg/s and exits at 1 MPa and 620 K. Determine the net power delivered to the generator by the turbine.
Two level sections of an east highway (G=0) are to be connected. Currently, the two sections of highway are seperated by a 4000-ft (horizontal distance), 2% grade.
A particle is traveling along a circular curve having a radius of 13 m. If it has an initial speed of 21m/s and then begins to decrease its speed at the rate of at = (-0.25s)m/s2
The United States Environmental Protection Agency (EPA) has published the following data for municipal solid waste generation (in millions of tons). Estimate a value of MSW generation in the year 2025.
A company manufactures a brand of light bulbs with a lifetime in month that is normally distribute with a mean=3 and a variance=1. A consumer buys a number of these bulbs with the intention of replacing them successively as they burn out.
One form of which consists of three equal weights joined by equal length ropes. The gaucho holds on to one weight spinning the bolas overhead. When the bolas is cast the weights cause the configuration to change
A cylinder with a 6.0 in., diameter 12.0 in. height is put under a compresive load of 150 kips. The modulus of elasticity for this specimen is 8000 ksi and Poisson's ratio is 0.35. calculate the final length and the final diameter of this specuman..
A cohesionless soil sample was subjected to a triaxial test. The sample failed when the minor principal stress (confining pressure) was 1200 lb/ft^2 and the deviator stress was 3000 lb/ft^2.
A power plant situated 20 km directly upwind from a protected old-growth forest emits SO2 at a rate of 120 g s-1with an effective stack height of 100 m (uH= 2 m s-1). Environmentalists claim that the acidic deposition is damaging the valuable fore..
List all the materials that you see, including different surface treatments and textures - Address all the transparent surfaces that might appear, how will model or show what is beyond those windows?
Two identical complete-mix activated sludge units are connected in series; one-half of the sludge recycle flow rate, QR, is recycled to the primary effluent pipeline which handles a flow rate Q, and the other half is recycled to the effluent line fro..
