The bent rod is supported at A, B, and Cby smooth journal bearings. Determine the magnitude ofF2 which will cause the reactionCy at the bearing C to beequal to zero. The bearings are in proper alignment and exertonly force reactions on the rod. Set F1 = 550 lb.
If the BOD5 of a municipal wastewater is 310 mg/L and the BOD U is 340 mg/L, determine the BOD reaction rate constant (base e). What would be the 3 day 30°C BOD Assume, temperature coefficient = 1.047.
Suppose you are a member of an EPA enforcement team investigating the possible dumping of arsenic into Arbor Lake. You take water samples from the middle of the lake and find that the concentration is 90.0 ppb.
a flat steel plate of 10mm thickness varies in width from 150mm to 300mm over a length of 1.5m. Determine the elongation of the plate under a tensile load of 250KN
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
Determine the factors of safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m l..
You are the winner of a sweepstakes and given a choice of a one-time payment of $1,000,000 or a guaranteed $80,000 per year for 20 years. Assume that you will collect all 20 years regardless of health condition.
Many years ago, well-known architect Frank Lloyd Wright designed a mile-high skyscraper, which has never been built.
Calculate the resistance coefficient K for a ball-type check valve placed in a 2-in schedule 40 steel pipe carrying 650 gal/min of oil (sg = 0.90)
Show how Kh, and Kow can be used to describe Koa. You must show how the concentration units for all equilibrium distribution ratios either cancel or remain to give the final value for Koa. Octonal-air partitioning coefficient (Koa = C(octanol)/C(a..
Collar A is dropped 30 inches onto collar B, which is resting on a spring of constant k= 4 lb/in. Assuming perfectly plastic impact (coefficient of restitution e=0), determine the maximum deflection of collar B.
