The elastic portion of the tension stress-strain diagram for an aluminum alloy. The specimen used for the test has a gauge length of 2 in and a diameter of 0.5 in. When the applied load is 9 kips, the new diameter of the specimen is 0.49935 in. Compute the shear modulus for the aluminum.
During a 1.5-hr storm, 1.3 in. of rain fell during the first hour, and 0.4 in. of rain fell during the last half hour. The average flow in the downspouts was 1.7, 3.6, and 3.4 ft3/sec for each of the half-hour periods.
what was involved in the first far-reaching, comprehensive study of Earth's oceans?
A particle of mass 200kg is lifted up vertically by a force of 104N. Assuming the acceleration due to gravity is 10meterper.secondsquare, write a program to calculate the upward acceleration of the particle.
Investigators have determined that the rate equation for bacterial kill in batch chlorine contact chambers is: rxn rate = dC/dt=-kCt where C is the concentration of bacteria, k is the rate constant, and t is time.
Determine the force required to lift the block of stone that weighs 200 lb. The rollers are frictionless and the static coefficient between all other surfaces is 0.3. Neglect the size and weight of the wedges.
At a certain location on the surface of an engineering component, the material is in a state of plane stress with principal stresses of fmax = 150 MPa and fmin = 50 MPa (both tensile). If the yield strength of the material is Y = 350 MPa
a wall 8 ft high is 3/3/8 ft. from a house. find the shortest ladder which will reach from the ground house when leaning to the wall.
The aluminum end and the copper end are maintained at temperatures of 50°C and 260°C, respectively. The thermal conductivities of aluminum and copper are 205 and 385 W/m · K, respectively. The temperature of the aluminum-copper junction in the rod..
compute normal and critical depths in a concrete culvert(n=0.015)with a diameter of 36in.and a bed slope of 0.002ft/ft if the design discharge is 15cfs.is the slope steep or mild?reap for S= 0.02ft/ft.
Water flows over a dam. Assume the volume flowrate per unit length q along the dam is a function of the head h , width b, acceleration of gravity g, f luid density and the fluid viscosity. Determine a complete set of dimensionless parameters
the 15,000 kg boxcar A is coasting freely at 1.5 m/s on the horizontal track when it encounters a tank car B having a mass of 12,000 kg and coasting at 0.75 m/s toward it. If the cars meet and couple together
A 4 mgd water treatment planet is being designed for an overflow rate of 0.5 gpm/ft^2. If two circular sedimentation basins will be used at al times, what should be the diameter of each basin
