For the mechanism shown in fig 8.81, link 2 rotate at a constant angular velocity. Determine the velocity and the acceleration of the slider and w32and alpha32 by a- using vector b- velocity an the acceleration polygon.
collar c moves along a circular guide with radius R=2ft with a constant speed v=18ft/s. at the instant, the bars AB and BC are vertical and horizontal respectively. Letting L=4ft and H=5ft, determine the angular acceleration of the bars AB and BC ..
a heat pump will be used to heat a building during the winter and will then cool the same space during the summer. the
the cylinder is made from steel where yield stress= 240 MPa and v=0.3. Subsequently sketch the hoop and radial stresses in the wall of the cylinder.
the collar has a mass of 20kg and is supported on the smooth vertical rod. the attarched springsare undeformed when d=0.5m determine the speed of collar after the applied force F=100N causes it to be displaced so that d=0.3m when d=0.5m, the colla..
