A W24×104 structural steel wide-flange section is used as a short compression strut and subjected to a vertical axial load of 350,000 lb, as shown.
Calculate the maximum load P that may be applied on the Y-Y axis at the outside face of the flange without exceeding the maximum compressive stress of 20,000 psi.
Consider the Helmholtz coil configuration shown in Fig. 2. Here R = 0.2 m,I = 10 A, and there are N = 100 windings in each coil. You can neglect the thickness of each coils windings so that its dimensions are fully specified by R.
Examine and measure the arms of three (or more) of your colleagues and develop average estimates of the distances b and L, and of the L/b ratio.
a well-insulated chamber is divided in two parts my a thin membrane. the left side with a volume of 2000 cm3 is filled
sterilization is a batch process by which bacteria and molds in food are killed by heat treatment. a can of vegetables
The rear two speakers each deliver 75 dB. Assuming all measurements are made at the same listener location, calculate the total SPL delivered to the listener. What percent of the total sound intensity (absolute value) is delivered by each speaker?
the rod of the fixed hydraulic cylinder is moving to the left with a constant speed. determine the corresponding
An axle-bearing surface made of high carbon steel has worn beyond its useful life. When it was new, the diameter was 4.00 in. In order to restore it, the diameter was turned to 3.90 in to provide a uniform surface.
What is the current factor of safety against a quick condition at A‘? (The FS is defined as the ratio of the critical gradient to the existing gradient).
Knowing that crank AB rotates about point A with a constant angular velocity of 900 rpm clockwise, determine the acceleration of the piston P when θ = 120°.
A hollow steel shaft has a 50-mm outside diameter and a 40- mm inside diameter. The shaft is 2 m long. Compute the angle of twist when the maximum shear stress is 52 MPa.
Two pounds of saturated water vapor at 400 F are condensed to saturated liquid in a piston-cylinder device. Calculate work done and heat transfer during this process, in Btu. Be sure to draw the process on a p-v diagram.
consider the following setup that sits in a room with a surrounding temperature of 25degc. the pressure and temperature
