Concrete pier is loaded on top with a uniformly distributed load of600 lbs per square foot. Investigate the state of stressat a level of 4 ft. above the base. Concrete weighs approximately 150 lbs per cubic foot. The total height of the block is 8 feet, the width is 2 ft, the bottom is 6 ft andthe top is 2 ft.
A rig accelerates a load of 200000 lbf from zero to 60 ft/min in 5 seconds. compute the load shown on the hook load indicator.
A real estate broker charges a fixed fee of $50 plus a 6% commission on the landowner's profit. If this is uniformly distributed between 0$ and 2000$, find the probability distribution of the brokers total fees.
a rectangular beam made using concrete with fc 6000 psi and steel with fy60000 psi has a width b 20 in. the concrete
A particle is moving with a velocity of Vo when s=0 and t=0. If it is subjected to a deceleration of a = (-K)v^3, where K is a constant, determine its velocity and position as functions of time.
A standard five-day BOD test is run using a mix consisting of fourparts distilled water and one part wastewater (no seed). Theinitial DO of the mix is 9.0 mg/L, and the DO after five days isdetermined to be 1.0 mg/L. What is BOD5 ?
Consider CO2 emissions from a gasoline powered vehicle. Gasoline is acomplex mixture of hydrocarbons but for the purposes of this calculation assume an average molecular formula of C7H16.
Draw the influence line for the shear in panel CD of the girder. Determine the maximum negative live shear in panel CD due to a uniform live load of 500 lb/ft action on the top beams.
If variable Test(i,j) is selected so the first column represents the student number (1,2,..., 32), 2nd column represents the score of the first homework, 3rd column represents the score of the 2nd homework, etc.
A closed box with horizontal base 6m x 6m and height of 2m is half-filled with water and is accelerated Ax=4.9 m/sec^2 and Ay=-2.4 m/sec. find the pressure at the forward and rear corners along the bottom.
