Contain at least one two-force member. Solve by utilizing the two-force principle, where appropriate. If the weight of a body is not specifically stated, it can be neglected. Determine the clamping (vertical) force applied by the tongs at E.
A carbon steel tank, 6ft. inside diameter X 10 ft. long with a 3/8 inch wall, is sitting on evenly spaced rolls and 4 evenly spaced supports (2 on each side). What is the horizontal force excerted on the supports? From the detail provided
a direct shear cell 25.4cm x 25.4 cm in plan is filled with dry sand. a normal load of 6kN is applied to the sample, and the shear failure is 3.5kN. What is the anle of internal friction for the sand
The load in the scoop of an excavator weighs 1.5 MN, and its center of gravity is at G. For the position shown, determine the forces in the hydraulic cylinders AB and CD.
A key part of the FEM and any FEA model are the appropriate assignment of boundary conditions. Explain why it is necessary to set the appropriate boundary conditions in FEA simulations. What happens if you don't assign boundary conditions or assig..
Crude oil (s.g.= 0.86, m =7.18*10-3 Pa*s) is to be carried at a flow rate of 0.25m3/s between two tanks with a difference of surfaceelevation of 9 m. The pipeline is smooth (e=0) and 90m long. What pipe size (diameter) is required?
At an angle of α=30°with the vertical, a 5kg sphere is suspended on a string of length .8m with a initial velocity of 1.2m/s, it colides with wedge B. ε=.7 between the .9kg wedge and sphere A.
the car weighs 2450 lb, the mechanical efficiency of the drivetrain is 90% and the wheel radius is 14 inches. the base engine develops 200 ft-lb of torque, and a modified version of the engine develops 240 ft-lb of torque.
Find the volume V of the solid bounded by the three coordinate planes and the plane 3x+2y+5z = 6 - Find the two coupled first order differential equations for the initial value problem.
A rectangular steel plate with thickness t=0.625 inches is subjected to normal stresses sigma x and sigma y.The strain in the x direction is known to be 0.00065 and the strain in the y direction is known to be 0.0004.
Now you want to improve the efficiency and circulation rate. You suggest operaing the cycle utilizing two reversible tubines with saturated vapor exit streams. All conditions remain the same except that the feed to the first turbine is steam at 450 C..
