The rocket is fired vertically and tracked by the radar station shown. When reaches 60°, other corresponding measurements give the values r = 30,000 ft, Calculate the magnitudes of the velocity and acceleration of the rocket at this position.
Some hypothetical alloy is composed of 12.5 wt% of metal A and 87.5 wt% of metal B. If the densities of metals A and B are 4.27 and 6.35 g/cm3, respectively, whereas their respective atomic weights are
When P = 800 lb, A) Draw the shear and bending moment diagram along its length; B) Determine the maximum tensile and compressive bending stresses; and C) determine the maximum shear stress.
How to detect eror in line of collimation and what does line of collimation means.
Design the continuous slab showin using the ACI moment coeficients assuming the service live load of 200 psf is to be supported in addition to the weight of the slabs
A bolt located 50 mm fm he center of an automobile wheel is tightened by applying the couple for 0.10 s. Assuming that the wheel is free to rotate and is initially at rest, determine the resulting angular velocity of the wheel.
a rectangular beam made using concrete with fc 6000 psi and steel with fy60000 psi has a width b 20 in. the concrete
The maximum and minimum dry densities, determined by standard laboratory tests, are 1.81 and 1.54 Mg/m^3, respectively. Determine the density index of the sand.
Weather records for a certain region indicate that there is a tendency for two hot summers to occur in a row. From the statistics for the region, the following information has been es tahlished
Compare the size of a CMFR (completly mixed flow reactor) and PFR (plug flow reactor) to achieve 50 percent removal of a contaminant, given a flow rate of 10^4 m^3/d and a first-order rate constant of -0.4/hr. Repeat for 99 percent removal.
a) Calculate the pore water pressure developed in the specimen at failure.b) What would the deviator stress at failure have been if a CD test had been conducted with the same confining pressure (i.e., 105 kPa)?
An A36 structural steel (36 Ksi yield strength) W8 x 40 member has been physically cut to 20 ft. long. This member is to be installed as a vertical column that supports a centric, axial compressive design load of 160.000 lbf and can be modeled as ..
Assuming a drag coefficient Cd of 0.6 for the baffle blocks based on the upstream velocity and combined frontal area of the blocks, calculate the sequent depth required to form a jump with the blocks and compare this value to the sequent depth requir..
