A W16 x 36 simply supported beam is 30 ft long and supports auniform dead load of 970 lb/ft, a roof live load of 240 lb/ft and asnow load of 270 lb/ft. Is this beam adequate to support the load?
a tank is filled with oil (specific gravity 0.8) and water to a depth of 10 meter and 6 meter respectively. Find the resultant force from all fluids acting on the gate of 1.8 meter by 9 meter.
Estimate the hourly production and unit cost of rock excavation by drilling and basting. The rock is limestone having a seismic velocity of 6000 ft/s. Trial blasting indicates that 3" holes drilled in 12 ft.
A torque of T = 3.00 kN-m will be applied to the hollow thin-walled aluminum alloy section. If the section has a uniform thickness of 4 mm, determine the magnitude of the maximum shear stress developed in the section.
Determine the minimum horizontal force necessary for 200 lb man to scale crevice (using his feet and back). The coefficient of static friction between his shoes and his back against the wall is 0.4.
Determine the vertical deflection in inches at the midpoint, called point F, between points B and C. Use E=29,000 Ksi, I=800 inches^4, and A=6.0 inches^2 for all members. Use the Virtual Work Method.
During the manufacturing process, a circular steel bar of diameter20mm and length of 1.2m is subjected to an axial load P. Themodulus of elasticity of steel is 207 GPa. The steel bar mustacquire an elastic strain energy of 14J.
A concrete beam that is simply supported sustains a uniform live load of 1.8 kips/ft and a uniform dead load (not including self weight) of 1 kips/ft on a span of 24 ft. Determine the layout for a set of No.3 U-stirrups with Fy=60 ksi and F'c=3.5 ..
Refrigerant 134a enters the compressor of a vapor compression heat pump at 15 psi and 0 °F and is compressed to 160 psi and 160 °F. Liquid enters the expansion valve at 160 psi and 95 °F. At the valve exit the pressure is 15 psi.
determine the maximum negative moment in each span and maximum negative moment at each support. remember that live loads shall be placed so as to cause the greatest effect. specify the method that you used to determine the moments.
The 81-lb uniform square plate is supported by a ball-and-socket joint at O, a cable at E, a fixture at A which can support vertical force only, and a linear spring at C. If the unstretched length of the spring is 4 in.
A water pipeline system is made up of three links in parallel. In any given year, on average, 99 in 100 pumps do not fail. The conditions in the links are statistically independent of each other.
If the outer ring rotates in the clockwise direction at 7 rpm and the inner ring rotates in the counterclockwise direction at 12 rpm, what is the angular velocity of the carriers and what is the velocity of C, the center of the top carrier.
