Small objects are delivered to the 72-in. inclined chute by a conveyor belt A which moves at a speedV1 = 1.2ft/sec. If the conveyor belt B has a speed V2 = 3.0ft/sec. and the objects are delivered to this belt with no slipping, calculate the coefficient of friction πk between the objects and the chute
While washing up Grandma's old aluminum cooking pot I noticed that it would just barely touch the bottom of the sink if I added 2.5 cups of water to it. The pot is 3.5 in high and 9.5 in diameter. Thickness of aluminum is 3/16 in.
the roller coaster track consists of a circle in a vertical plane of radius 150m. find the magnitude of the total acceleration of the roller coaster if, at the time shown, the car is moving at 50 km/hr and is gaining speed at the rate of 0.4g
Compute the motor size required to pump 28.3 cms through a 3,050 m long, 3.66 m diameter pipeline to an upper reservoir 610 m above the lower reservoir. Use a friction facter of 0.02 and a pump efficiency of 80 percent.
Calculate the surface area (m2), diameter (m), volume (m3), and hydraulic retention time of a 3 m deep circular, primary clarifier that would remove 50 percent of suspended solids. Assume the surface overflow rate (SOR) used for design is 60 m3/m2-..
The ¼" thick 6061?T6 aluminum bar is subjected to a tensile force of P = 5 kips. b = 4"; c = 1.5"; d = 2.5"; and the fillet radii are 1". a) Determine the maximum stress in the bar. b) What is the lateral strain in the 1.5" wide section
Why don't we assume that there is an unknown moment about B? It the solution it only shows a horizontal force at B. And is there a reason why the horizontal force at B is labeled By?
Determine the normal force, shear force and bending moment at point D for the 3-pinned - Determine the deflection at C using the strain energy method - determine the deflection at the free end C for the beam.
It is known that the velocity distribution for steady, laminar flowin circular tubes (either horizontal od vertical) isparabolic. Consider a 10 -mm- diameter horizontal tubethrough with ethyl alcohol is flowing with a steady mean velocity.15 m/s.
Parallel pipes, fixed overall H, ?EGL or hl = 75'. Elevated Tank A water surface is at El 625, 3000' away is Tank B with free surface El 550 They are connected by a 12" dia cast iron pipe.
a layer of sand 4 m thick, overlies a layer below permeability clay, 5m thick. the bulk unit weight of the sand is 16.5 KN/m^3 and its saturated unit weight is 18 KN/m^3. the saturated unit weight of the clay is 21 kN/m^3.
