A short reinforced concrete column 250mm square carries an axial load of 30 Mg. the column is reinforced with 40 mm diameter bars. if the modulus of elasticity for steel is fifteen times that for concrete, find the stresses in the steel and concrete. If the concrete stress must not exceed 3.9N/mm square what area of steel is required for the column to support60Mg
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.
A suppressed rectangular weir is being used to measure flows in anirrigation canal. The weir is 5 m wide and 2m high and, under floodconditions, the upstream and downstream depths are measured at 2.5mand 2.3 m, respectively.
Instruments in airplane A indicate that with respect to the air the plane is headed 30 degrees north of east with an air speed of 480 km/hr. At the same time, radar on ship B indicates that the relative velocity of the plane with respect to the ship ..
Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your concrete project?
Cartridges cost $120 each and require 2 weeks to obtain from the vendor. Jill uses (Q,r) policy to control inventory of cartridges. You can assume that there are 50 working weeks in a year.
Compute the velocity of a free-falling parachutist using Euler's method for the case where m = 80 kg and c = 10 kg/s. Perform the calculation from t = 0 to 20 s with a step size of 1 s. Use an initial condition that the parachutist has an upwar..
A business wishes to discharge salt into a river. the concentration of salt from the business is 210 mg/L. the flow of water in the river (upstream) is 0.5 m^3/s. Upstram the concentration of salt in the river 15 mg/L.
Part B (Assignment): by trial and error, find the angle that will give the minimum force F to make a basket (hint: try 52 degrees)The trajectory of the ball will make a basket when x = L and y = Hb
A 4-m- long, 6-cm-diameter cylinder placed normal to the flow is used to measure the velocity of an air stream. If a force of 50N is measured. What is the air velocity in m/s?
How to draw bending moment diagram for this shape and the value of the moment in critical sections assume that the distributed load (w) KN/M and the concentrated load
A 3 kg mass is attached to one end of a 1 m long cord. The other end of the cord is attached to the center of a rotating disk (with radius greater than 1 m) that has a very large constant angular velocity.
If the coordinate direction angles for F3 are a=120degrees, b=45degrees, y=60degrees, determine the magnitude and coordinate direction angles of the resultant force acting on the eyebolt.
