Velocity and Acceleration Analysis of mechanism
The mechanism in Fig. 5.54 has the dimensions: AB=200 mm, AC=600 mm, BD=1000 mm, La=150 mm, and Lb=250 mm. The driver link 1 rotates with a constant angular speed of n=60 rpm. Find the velocities and the accelerations of the mechanism for phi=phi1=120.
water is the working fluid in a vapor power cycle with superheat and reheat. superheated vapor enters the first turbine
The cantilevered bar in the figure has a circular cross section and is subject to bending and torsion. The normal stress due to bending in x=28 kpsi and the shear stress due to torsion is xz=15.3 kpsi. The change in diameter introduces a stress conce..
water flows 2m deep at 2ms in a rectangular channel. find the change in depth and in water surface elevation caused by
The power output of an ideal, open-cycle gas turbine cycle is 75 MW and its pressure ratio is 16. Air enters the compressor at 520 R and enters the turbine at 2800 R. Using variable specific heats at 1000°F: cp = 0.263 Btu/lbm-R and k = cp/cv = 1.353..
A horizontal platform rests on four vertical springs, each of stiffness 15kN/m and mass 0.25kg. what will the frequency of oscillation of the table be if it has a mass of 2.okg
Two collars C and D move along the vertical rod as shown. Knowing that the velocity of collar C is 50 in/s downward, find the instant centers of all three bars, the angular velocity of AB, the velocity of collard D.
