A W14x34 section is used as a simply supported beam over a span of 20 ft. The beam is loaded with a concentrated live load of 10 kips at the center of its span, in addition to its own weight.. The dead load includes the beam weight. The steel is A242, Grade 50. Check the shear resistance of this beam. Use the ASD design method only.
A worker is to paint the walls of a square room 8ft high and 12 ft along each side. what surface area in square meters must she cover?
Describe a dynamic programming algorithm to find an independent set of T such that the sum of numbers of nodes in the set is the largest among all possible independent sets of T.
water from a reservoir is being supplied to a powerhouse that is located at an elevation 935 ft below that of the reservoir surface. Discharging through a nozzle, the water has a jet velocity of 240 fps and a jet diameter of 6 in.
a new sports car has a drag coefficient of 0.30 and a frontal area of 21 ft^2, and is traveling at 119 mi/h. how much power is required to overcome aerodynamic drag if p = 0.002378 slugs/ft^3
The sodium cyanide solution ([NaCN]-total = 0.01 M) is kept at pH 10.4. The pH is kept high to keep the cyanide in the CN- form. If CN protonates by the reverse of the HCN dissociation reaction,
A force, 90 N in magnitude, is applied to control rod AB as shown. Knowing that the length of the rod is 225 mm, determine the moment of the force about point B by resolving the force into components along AB and in a direction perpendicular to AB..
