The rig shown consists of a 1200-lb horizontal member ABC and a vertical member DBE welded together at B. The rig is being used to raise a 3600-lb crate at a distance x=12 ft from the vertical member DBE.If the tension in the cable is 4 kips, determine the reaction at E assuming (a) anchored at F as shown in the figure, (b) attached to the vertical member at a point located 1 ft above E.
assume that the earth is a smooth sphere and a steel band wrapped around the equator. if 10ft of steel is spliced into the band, what will be the resulting height of the band above the earth surface
engineering ethics course where we have to select a case related to civil engineering with reference to it and discuss
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.
The 3.5-Mg engine is suspended from a spreader beam having a negligible mass and is hoisted by a crane which exerts a force of 40 kN on the hoisting cable. Determine the distance the engine is hoisted in 2.4 s, starting from rest.
the casting has a mass of 3 mg. suspended in a vertical position and initially at rest it is given an upward speed of v
At what point on the expressway should the motorist step on her brakes in order to reduce her speed to the maximum allowable on the ramp just before entering the ramp
A rectangular channel leading from an upstream lake has a bottom width of 20 ft, bottom slope of 0.0002, a Manning roughness factor of 0.016, a discharge of 403 cfs, and normal depth of 6.24 ft.
Water flows through a 250-mm diameter steel (C=120) pipe at a a velocity, V = 1.5 m/s. Using the Hazen-Williams equation, what is the head loss due to friction per 1000 m of pipe
determine the pressure head at the nozzle inlet to produce a water jet velocity of 40 ft/s. Neglect the friction loss and assume incompressible flow.
Draw the shear and moment Diagram for a beam that is 10 feet long, supported on the left end by a roler, and the right end by a pin, and has a 1000 lb load placed in the center i.e at 5 feet.
The compound interest formula is F=P(1+i)n where F is the total amount due, P is the initial cost or amount of money, i is the interest rate, and n is the number of periods interest is computed. 1.A student purchases a $1400 laptop computer for sc..
An in-compressible fluid flows horizontally in the x-y plane with a velocity given by u = 33 (y/h)^1/2 , where y and h are in meters and h is a constant. Determine the average velocity for the portion of the flow between y = 0 and y =h.
