A circular cam is in contact with a rectangular lifter and used to intermittently operate a piece of equipment at the end of a lifter arm. The lifter is constrained to move only in the vertical direction. The cam has a radius of r = 7.2in and is rotating about point O, which is offset from the center by a distance c = 3.9in . The cam’s angular position is measured from the positive x axis and is positive clockwise. The angular velocity and acceleration are positive clockwise. Find the linear velocity of the lifter with respect to point O when the cam has an angular position of ? = 25? and is rotating with an angular velocity of ? = 3.1rad/s . Find the linear acceleration of the lifter with respect to point O when the angle is ? = 25? , the angular velocity is ? = 3.1rad/s , and the angular acceleration is ? = 2.0rad/s2 .
Stormwater controls are typically designed by civil engineers. Stormwater is collected in pipes below the ground and routed to nearby surface water.
Estimate the value of the coefficient of at-rest earth pressure forthe deposit. If, when the water table was at the ground surface, the deposit was normallyconsolidated,would it still be normally consolidated with the water tablelowered? A reason mus..

Seawater flows steadily into an open 100 liter tank initially filled completely with freshwater. The freshwater mixes thoroughly with the seawater and the mixture overflows out of the tank.
The top of the object is 1 m below the surface of the fluid. What are the magnitude and direction of the hydrostatic force acting on the top of the object.
A room has 10 cotton spinning looms. Once the looms are set up, they run automatically. The setup time is exponentially distributed, with mean 10 minutes. The machines run for an average of 40 minutes, also exponentially distributed.
Develop the mass balance equation and solve for the deficit concentration as a function of x, u, Lo, Do, ka, kd,and ks in the stream. Lo ans Do are the initial concentrations of BOD and DO deficit in the stream at x
Determine the maximum pressureallowed in the pipe at a location 10 m above the pipe exit if the flow is to be laminar.

Saturated liquid water at 1.0 MPa is throttled adiabatically to a pressure of 0.4 MPa. If the change is kinetic energy is negligible, what percentage of the water evaporates during this throttling process?
A scientist plans to build a water barometer. When the atmospheric pressure is 990 mb abs and the water temperature is 70 degrees Celsius, what would you expect the barometer reading (water rise) to be
