The right-angle bar with equal legs weighs 6.3 lb and is freely hinged to the vertical plate at C. The bar is prevented from rotating by the two pegsA and B fixed to the plate. Determine the acceleration a of the plate for which no force is exerted on the bar by either peg A or B.
A water tank has a height of 120m, and its area of cross-section is 2000m. Water is released from the tank and the water level drops by 1 meter every minute. Find the rate of change in volume.
Ethyl acetate is made from acetic acid and ethyl alcohol. Let x = pounds of acetic acid input, y=pounds of ethyl acohol input, and z = pounds of ethyl acetate output. The relationship of output to input is: z^2/(1.47x - z)(1.91y - z) = 3.9.
A pile resists the tension developed by three stay cables for a major tent (Membrane) Structure. Assuming no bending is desired in the pile (no resultant horizontal component), what is the magnitude of the force S if the angle \thetaS = 30 degrees

Suppose that all the dislocations in 1000 mm^3 (1 cm^3) were somehow removed and linked together end-to-end. How far (in miles) would this chain extend
A freeway has a capacity of 4500 veh/hr. A traffic accident occurs at 9AM and the freeway is closed. At 9:15 AM, the freeway is partially opened with capacity of 1500 veh/hr. Freeway is restored to full capacity 4500 veh/hr at 9:30 am.
Car B is driving straight toward the point O at a constant speed v. An observer, located at A, tracts the car with a radar gun. What is the speed |r(dot)B/A| that the observer at A records
Find the steel area required for beam which has b = 10 in. and d = 17.5 in. to carry a factored load moment of 1,600 in-kips.
using darcy's law compute the quantity of flow, seepage velocity and contaminant loading of the river. ground water is flowing through unconfined uniform 3m thick sand aquifer and discharging to river.
Working a problem where there are two one-story buildings of different heights next to each other. Earthquake imparts a base motion z(t) that is a cosine function. I'm given a shape function for a column of height L when deriving the EOM for each ..
Use input values of epsilon (B1), pipe radius (B2), and Reynolds number (B3) to estimate "f" and place these in the same cells . Display the final answer in a message box and round to five figures. Use a short cut key of Ctrl+g
