You are given that a piece of rope is 90.5 ft long. The distance between the poles holding the rope is 90 ft. Find the tensions in both sides of the rope for someone walking across the rope and the deflection for every 0.5 ft up to 45 ft. much like the problem in our book(2.C7, Vector mechanics for engineers:statics). Setting the problem up to find the deflection as the person walks across the rope.
A 40lb, .8ft diameter, 1ft tall cylindrical tank slides slowly down a ramp with a constant speed of .1ft/s. The uniform-thicknessoil layer on the ramp has a viscosity of .2lb*s/ft^2.
The suspended load exerts a force F = 600 lb at A and bar OA weighs 200 lb. Assume that the bar's weight acts at its midpoint. Determine the tensions in the cables and the reactions at the ball and socket support O.
how many students have heights, (a) Greater than 72 inches (b) Less than or equal to 64 inches (c) Between 65 and 71 inches inclusive (d) equal to 68 inches * Assume the measurements to be recorded to the nearest inch.
Ammonia is a gas whose smell we detect in manure, cleaning products, and other things. The concentration of this noxious gas can be controlled by regulating the pH of the water because only the non-protonated form, NH3, is volatile.
Calculate carbonate, noncarbonate, and total hardness Na+ = 27.8 mg/L Cl- = 35.6 mg/L Ca+2 = 48mg/L CO3-2 = 30 mg/L Mg+2 = 12mg/L HCO3- = 61 mg/L K+ = 12 mg/L SO4-2 = 48 mg/L
A trapezoidal channel is to be designed to carry a discharge of 250 cfs at a normal depth of 3.5 ft. The channel is running on a slope of 0.005 ft/ft and the side slopes can be no steeper than 2.5 H on 1 V.
