The electric motor at A exerts a torque of 800N.m on the steel shaft from A to D. This has a torque of -300N.m at B and -500N.m at C. the dimensions are
shaft(a-b)=0.4m
shaft(b-c)=0.6m
shaft(c-d)=0.3m
Design specificaions require that the diameter of the shaft be uniform from A to D and that the angle of twist between A to D not exceed 1.5 degrees.
Knowing that the masximum shear stress must not be greater than or equals to 60Mpa, and G= 77GPa, determine the minimum diameter shaft that can be used.
It is desired to obtain dynamic similarity between 3 cfs of water(ρ = 1.94 slug/ft3, μ= 2.735 x 105Ibs/ft2) flowing in a pipe and oil 9s.g = 0.91, μ=12 x 105 ibs/ft2) flowing in a 12in diameterpipe at a velocity of 25 ft/s at 90 deg F. What size of p..
After the Chernobyl accident, the concentration of 137Cs in milk was proportional to the concentration of 137Cs in the glass that cow consumed. The concentration in the grass was, in turn, proportional to the concentration in the soil.
1. The three isometric axes are: vertical and two axes 30 degrees from horizontal. 2. Oblique projection is a perspective projection method. 3. Isometric view represents a parallel projection method.
A gas occupise 250 ml and it's pressure is 550mm Hg @ 254C how many moles of gas are in this sample? (convert mm Hg to atm).
A rigid horiztonal bar is suspended from two springs and is subjected to a vertical force of F0 = 158.8 kips. Each spring has a stiffness k = 14.7 kips/inch. If L1 = 11 inches and L2 = 11 inches, use strain energy to calculate the deflection of th..
What is the water content and liquidity index of the fines in compacted mass?A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long.
Determine the stability of the wall before and after the rainfall. Neglect seepage effects and which of the two walls in Figure gives the large horizontal force
For the FE pin-pin cable model, solve for the deflection and reactions using the partitioned form. What is partitioned form
The car's gear reduction ratio is 3.5 to 1, driveline efficiency is 90%, driveline slippage is 3.5%, and the road-wheel radius is 15 inches. What will the car's maximum acceleration be under these conditions on a level road
Assuming the following equation represents the true distribution in the vertical, determine the actual distance below the surface at which the velocity, u, equals the depth-averaged velocity, U.
The total volume of the house is 650 m3 (assume that the volume is well mixed throughout). The radon source emits 250 pCi/s (A picoCurie [pCi] is a unit proportional to the amount of radon gas and indicates the amount of radioactivity of the gas)
