A square plate of uniform thickness has a side length of 25 cm that hangs vertically from hinges at its top edge, When horizontal jet strikes the plate at its center, the plate is deflected and comes to rest at an angle of 30o to the vertical. The jet is 2.0 cm in diameter and has a velocity of 8.0 m/s. Calculate the mass of the plate. What force should be applied at the lower edge of the plate to maintain its vertical position?
Consider the two loading scenarios on the beam, where the beam is supported by a pin joint on the left and roller joint at the right end. What are the internal forces and moment at point A for each scenario
If they plan to increase their savings by 5% each year, how much must they invest in the first year given that they expect to earn 4% per year on their investment?
At a local engineering firm, a supervisor thinks about buying a new copy machine for $700 but only wants to keep it for 3 years. Using the DDB find the book value of the machine at the end of 2 years.
A pump is to be used to draw seawater from the bay at an elevation of 0 to a reservoir at a desalination plant that has a water surface elevation of 255 feet. A 12-inch diameter DIP pipe (CHW = 120) which is 625 feet long connects the two bodies ..
Calculate the compacted cubic yards per hour if a compactor with a 5-ft drum width travels at 3 mph over a 10-in. lift of aggregate base course with 4 passes required to meet density specifications under average operating conditions.
Calculate the largest tolerable internal crack length for a 7075-T651 aluminum alloy component that is loaded to a stress one-half of its yield strength without catastrophic fracture.
Assuming unit surface area, find the conductive heat loss through the furnace wall and the temperature at the interface of the fire clay and red brick.
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
The maximum gage pressure is known to be 8MPa in a spherical steel pressure vessel having a 250mm diameter and a 6mm wall thickness. Knowing that the ultimate stress in the steel used is (sigma u)= 400MPa, determine the factor of safety with respe..
For any flowrate, the pressures in the pipes upstream and downstream of the reducer are expected to be related by using Bernoulli's equation where p1 and p2 are the upstream and downstream pressures and V1 and V2 are the upstream and downstream ve..
