1.The rate of flow through a trapezoidal open channel is 20 m^3/s and the mean velocity of flow is m/s . the side slope is 1:1 and the bed slope is 1 in 5000. Assume Chezy's constant C as 60, find the bottom width and the depth of water channel.
2.A simply supported beam carries with a span of 7.5 m carries a uniformly distributed load of 25 N/mm. if the maximum allowed deflection of the beam is 1/325 of its span, detemine the cross-sectional dimensions of the beam. assume the beam has a rectangular cross-section with an aspect ratio of 4. verfiy your design against defection?
The base engine develops 200 ft-lb of torque, and a modified version of the engine develops 240 ft-lb of torque. If the overall gear reduction ratio is 8 to 1, what is the maximum acceleration from rest (in ft/sec^2) for.
A 20-lb package is thrown with a speed of 9 ft/s onto the 100-lb cart at the given angle of 30 degrees. It slides on the smooth cart and strikes the spring. If the spring has a spring constant k= 200 lb/in
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 steel bar of length 30 inches and circular cross section whose diameter varies linearly from 0.50 inches at one end to 0.75 inches at the other is subjected to an axial tensile force of 4.5 kip. Find the change in length of the bar.
A tiler is removing broken tiles from the roof of a house, and throws a tile with a velocity of 8 m/s at an angle of 20 degrees above horizontal. At the point of release the tile is 5.2 m above the ground surface.
If a new piece of equipment costs $40,000.00 to purchase and it has a benfit of $500 per day. How many days per year does the equipment need to be used in order to be worth purchasing (breaking even)
A soil sample with a volume of 0.5 m3, dry unit weight = 18.1 kN/m3, water content = 5%, and Specific Gravity of the soil solids = 2.68. Calculate weight of water added to reach 90% saturation (in kilograms)?
