A simply supported beam (one end has a pin support and the other a roller support) is 10 ft long. The width of the beam is 3.5 in. The beam supports three concentrated loads (2.5 kips 2 ft from A to B, 1 kip 5 ft from A to B, and 2.5 kips 8 ft from A to B). The allowable bending stress in the wood is 1800 psi and the allowable shear stress is 120 psi. Determine the minimum required depth of the beam.
A rod of steel is 20 m long at a temperature of 200C. find the free expansion of the rod when the temperature is raised to 65 0 C. Find the temperature stress produced
In trigonometric leveling from point A to point B, the slope distance and the zenith angle measured in A were 2504.897 m and 85o08'54". At B, these measurements were 2504.891 m and 94o52'10" respectively.
Chemical ‘A' is regulated by EPA and the maximum allowable concentration in water is 5 ?g/L. Design a reactor for a water treatment plant where 1000 ppm of chemical ‘A' is introduced at a flow rate of 100 m3/min.
The left-hand span is 16 ft and the right-hand span is 20 ft. The beam supports a uniform load of 900 plf, which includes its own weight, over the entire 36 ft and also a concentrated load of 10,000 lb applied at a point that is 5 ft from the left..
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t Cedar points millennium force accelerates from 10 mph to 93 mph in 4.5 seconds. assuming acceleration is constant, find acceleration in ft/sec^2 and distance traveled in meters
A canal was constructed running parallel to a river 1500 ft away. Both fully penetrate a sand aquifer with a hydraulic conductivity of 1.2 ft/d. The area is subject to rainfall of 1.8 ft/y and evaporation of 1.3 ft/y.
Find the length and width of a square basin for virus disinfection of a flow of 6 MGD. You may assume a depth of 5 ft, a C(dot)t product of 10 (mg/L) (dot)min for 1.5-log removal, and a target free chlorine residual of 0.6 mg/L.
The truck is driving onto the stationary barge at the speed of v1. The masses of the truck and the barge are m and M, respectively. The barge is free to move on the water and the water resistance is to be ignored.
Your response should be a minimum of one (1) single spaced page to a maximum of two (2) pages in length. Explain the process for establishing a centerline for a roadway for an existing road.
The flywheel rotates with an angular velocity of omega = (4*theta^(1/2)) , where theta is in radians. Determine the time it takes to achieve an angular velocity of omega = 190 rad/s . When t = 0, theta = 1 rad .
a spherical pressure vessel has an outer diameter of 10 ft and a wall thickness of 0.5 in. knowing that for the steel used ?all= 12 ski, E= 29 x 10^6 psi, and v= 0.29, determine (a) the allowable gage pressure,
if a source of groundwater gets contaminated with a DNAPL and another one gets contaminated with a LNAPL, which one will be harder to remediate and why
