The 200-kg block D is dropped from a height h = 1 m onto end C of the A992 steel W200 × 36 overhang beam. If the spring at B has a stiffness k = 200 Kn/m, determine the maximum bending stress developed in the beam.
Plot the ground level concentration of sulfur dioxide as a function of distance from the stack and determine the maximum ground level concentration at both with and without air pollution control and the distance from the stack where the maximum co..
Calculate the stress at failure of a concrete test cylinder with a measured diameter of 152.4 mm and a recorded load of 371,426N. Units of ksi.
As the pressure on the valve increases, a force of 14.0 lb causes the valve to open and compress the spring to a length of 1.25 in. Use corrosion-resistant ASTM A313. Type 302 steel wire, and design for average service.
Heat is now added until the quality is 40 percent. Determine the minimum entropy change of the thermal energy reservoir supplying this heat.
A 27ft beam has a uniform load of 6kip/ft. along its entire length. From left to right x=0ft to x=27ft. At x=0 ft it is pinned and at x=18 ft there is a roller. So, the 9 ft end section is cantilevered. What is the maximum bending moment of the beam?
Consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam. Assume, length L, flexural stiffness EI, and mass m.
In the accompanying diagram (which represents the market for chocolate candy bars), the initial equilibrium is at the intersection of S1 and D1. a. Circle the new equilibrium if there is an increase in cocoa prices.
A pharmaceutical wastewater needs a minimum of BOD/N/P of 100:5:1 for biological treatment. the wastewater characteristics are BOD= 800 mg/l, among which 95 % are soluble, suspended solids 250 mg/l, soluble nitrogen as element nitrogen = 24 mg/l, and..
Visit a construction site where concrete work is going on. Examine the forms, reinforcing, and concrete work. Observe how concrete is brought to the site, transported, placed, compacted, and finished. How is the concrete supported after it has bee..
Compute the volume flow rate required to produce a Reynolds number of 3.60 x 10 ^4. then, if the pipe is clean steel, compute several points of the velocity profile and plot the data.
