Consider the simply supported beam that has one external load applied to it. At a cross- section that cuts through the carriage bolt, there are 5 points at which the states of stress must be identified. The section is .001 mm to the right off the center of the carriage bolt (this will set the direction of shear).
-Draw the 5 stress-elements using the natural orientations conforming to the shape of the beam.
-Establish the direction of the stresses.
What return period must an engineer use in the design of a bridge opening for a 50% risk that flooding will occur at least once in two consecutive years? Repeat for a risk of 100%.
The 2 Mg car is being towed by a winch. If the winch exerts a force of T=105s on the cable, where 14m is the displacement of the car in meters, determine the speed of the car when s , starting from rest. Neglect rolling resistance of the car.
The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7, Calculate the amount of heat transferred during the process in Kj.
The maximum speed of trains for urban rail transit is 60 mph and maximum acceleration/deceleration rates allowed for standing passengers are 5 feet/sec2. Part A) If the station spacing is determined at 1000 ft, what is the maximum average running s..
The owners wish to achieve an initial acceleration from rest of 22 ft/(sec^2) on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve this acceleration
design a rectangular reinforced concrete beam (tension steel only) for the span and superimposed service loads shown. use f'c=5000psi and A615 grade 60 steel. LL=3.5 k/ft over the first 12 feet of the beam
A pre- engineering base line was run down a very steep hill.rather than measure horizontaily down hill with steel tape: surveyor measured the vertical angle with the theodolite and slope distance with 16m steel tape.
A cylindrical water tank is suspended vertically by its sides. The tank has a 10-ft diameter and is filled with 20 degree celcius water to a 3-ft depth. Determine the force exerted on the tank bottom
The 12 in diameter cast iron pipe is 2000ft long, the water surface is El 200 in the reservoir on the left B. El 175 on the right. A. Find V and Q by hazen-williams for a new cast iron pipe (Chw=130) Neglect entrance, exit and local losses.
A consolidated-drained triaxial shear test on a normally consolidated clay yielded a drained friction angle of 28 degrees. If the confining pressure during the test was 15 psi, what was the major principal stress at failure.
Given an 18-in. concrete conduit with a roughness coefficient of n = 0.013, s = 0.02, and a discharge capacit of 15 cfs, what diameter pipe is required to triple the capacity
