The member OA of the industrial robot telescopes and pivots about the fixed axis at point O At the instant shown, 6m/s2Determine the magnitudes of the velocity and acceleration of joint A of the robot. Also, sketch the velocity and acceleration of A and determine the angles which these vectors make with the positive x-axis. The base of the robot does not revolve about a vertical axis.
A belt is wrapped around a pulley for 180 degrees. The loose-side belt tension is 100 lb and the coefficient of static friction is 0.30. Calculate the maximum belt tension if motion is impending. Assume A) a flat belt and B) a V-belt with a groobe an..
Annual rainfall over the watershed is 36 inches and the annual runoff from the catchment is 12 inches. Evaporation from the reservoir averages 40 inches per year. The municipal water demand equals 100 million gallons per day

a rectangular swimming bath is 1m deep at one end and increases uniformly in depth to 2.6m at the other end . the bath is 8m wide and 32m long and is emptied through an orifice of 0.2m^2 at its lowest point.
A buried horizontal concrete pipe (n=0.012) of unknown length needs to be replaces. the length is not known because the original plans for the pipeline route have been lost.
The compound interest formula is F=P(1+i)n where F is the total amount due, P is the initial cost or amount of money, i is the interest rate, and n is the number of periods interest is computed. 1.A student purchases a $1400 laptop computer for sc..
The first stratum is confined, and the second one is unconfined, and the water surface elevations in the channels are 24 m and 16 m above the bottom of the unconfined aquifer.
Apiece of corroded steel plate was found in a submerged ocean vessel. it was estimated that the original area of the plate was 62.5cm 2 and approximately 2.8k had corroded away during the submersion.
Communication satellites are placed in a geosynchronous orbit i.e in a circular orbit such that they complete one full revolution about the earth in one sideral day (23.934h), and thus appear stationary with respect to the ground.
Consider a Carnot heat-engine cycle executed in a steady-flow system using steam as the working fluid. The cycle has a thermal efficiency of 35%, and steam changes from saturated vapor at 300 C during the heat addition process. If the mass flow rate ..
