The rod OA rotates clockwise with a constant angular velocity of 6 rad> s. Two pin-connected slider blocks, located at B, move freely on OA and the curved rod whose shape is a limaçon described by the equation r = 200(2 - cos u) mm. Determine the speed of the slider blocks at the instant u = 150°.
12-173. Determine the magnitude of the acceleration of the slider blocks in Prob. 12-172 when u = 150°.
*12-176. The car travels around the circular track with a constant speed of 20 m> s. Determine the car's radial and transverse components of velocity and acceleration at the instant u = p>4 rad.
12-177. The car travels around the circular track such that its transverse component is u = (0.006t2) rad, where t is in seconds. Determine the car's radial and transverse components of velocity and acceleration at the instant t = 4 s.
An air-standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes: Isentropic compression from 100 kPa and 27 degrees C to 1.11 MPa. P = constant heat addition in amount of 3,020 kJ/kg
During this process, heat is transferred from a heat source at 200oC, such that when the valve is closed, the temperature inside the tank is 50oC. What is the heat transfer?

a rigid 2 m3 tank contains air at 160oc and 400 kpa and a relative humidity of 20. heat is removed until the final
liquid methanol is pumped from a large storage tank through a 1.256 inch id pipe at a rate of 3.00galmin.a at what rate
A fixed amount of moist air initially at 1 bar and a relative humidity of 60% is compressed isothermally until condensation of water begins. Determine the pressure of the mixture at the onset of condensation, in bar. Repeat if the initial relative..
Obtain a formula for the maximum permissible angle a if there is to be no tensile stress in the tower.
Explain why change is inevitable in complex system and give examples of software process activities that help predict changes and the software being developed more resilient to change.
An air compressor operates under steady conditions. Air is compressed from an initial state of 295 K and 101 kPa to a final state of 430 K and 340 kPa. Ignore heat transfer between the compressor and surroundings and ignore kinetic energy and potenti..
Using a control volume analysis of mass and vertical momentum, derive the differential equation for the downward motion V(t) of the liquid. Assume one-dimensional, incompressible, frictionless flow.
