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.
The bar DA is rigid and is originally held in the horizontal position when the weight W is supported from C. If the weight causes B to be displaced downward 0.025 in., determine the strain in wires DE and BC. Also, if the wires are made of A-36 steel and have a cross-sectional area of 0.002 in^2, determine the weight W.
A variable-order reaction A-->B has the following rate expression: R(a) = -kC(a)/(K+C(a)) where k = 5mg/L-hr and K=40mg/L The reaction is to take place in a batch reactor. The initial concentration is 450 mg/L
There are no interchanges in the vicinity of this freeway segment. If the peak-hour factor is .90 and all of the drivers are regular users, what is the level of the service of this compound-grade freeway segment?
The velocity of flow toward the sphere along the longitudinal axis is found to be u = - U0 (I - r~/_xl), where r0 is the radius of the sphere and x the distance from its center.
Assuming that the CPI (82-84) for March 2013 is 232.773, and your starting salary is $55,000. How much would your starting salary have been in 1983 (assume CPI=100).
Determine the design load for strength and serviceability limit states (short-term and long term), for a steel beam in a residential building with the following data;
If the temperature of rod CF is increased by 10 degrees C and that of rod BC is decreassed by 40 degrees C, determine the normal stress in rod AD. The rods are two meters long.
A lagoon with volume 1200 m3 has been receiving a steady flow of a conservative waste at a rate of 100 m3/day for a long enough time to assume that steady-state conditions apply.
Assume you are responsible for determining the maximum load that can be carried by a rectangular barge that is 8 m wide and 18 m long. The water line when the barge is empty is 3 m below the level of the cargo deck.
the stress at a point is shown on the element. Determine the principal stresses and the absolute maximum shear stress.
An electronic device is available that will reduce year'slabor cost by $10,000. the equipment is expected to last for eightyears. If labor is cost increase at an average rate of 7% per yearand the interest rate is 12% per year
Draw a picture of a typical strain gauge and point out the major components. Give a short explanation on the principal behind how a strain gauge works.
The volume and the average density of an irregularly shaped body are to be determined by using a spring scale. The body weighs 7200 N in air and 4790N in water. Determine the volume and density of the body.
