The rated speed of drum B of a belt sander is 2400 rpm. When the power is turned off it is observed that the sander coasts from its rated speed to rest in 10 s. Assuming uniformly decelerated motion, determine the velocity and acceleration of point C of the belt, (a) immediately before the power is turned off. (b) 9 s later.
If the elevation difference between the water surfaces is y = 25 + x/11 metres, what minimum pipeline diameter will be required to convey the design discharge? Once your design is complete, determine the actual discharge. The value of x equals 23.
The height (in meters) of a projectile shot vertically upward from a point 2 m above ground level with an initial velocity of 24.5 m/s is h2+24.5t-4.9t^2 after t seconds. a) When does the projectile reach its maximum height? b) What is the maximum..

Determine the number of man-hours required to form the structure using data from R. S. Means or other appropriate reference. What is the difference between labor cost and labor pro-ductivity?
Consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam. Assume, length L, flexural stiffness EI, and mass m.
In using the Darcy-Weisbach equation for flow in a pressure conduit, what percentage error is introduced in Q when f is misjudged by 20 percent?
There are 10 vehicles in a queue when an attendant opens a toll booth. Vehicles arrive at the booth at a rate of 4 per minute. The attendant opens the booth and improves the service rate over time following the function u(t) = 1.1 + .30t, where u(..
Determine the transformed moment of inertia for the beam using steel as the reference material. Express your answer in in^4 to the nearest 0.1 in^4.
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
Water with a static pressure of 1.96kN/M 2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M 2 . How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/se..
