6.
The scaffold S is raised hydraulically by moving the roller at A towards the pin at B. If A is approaching B with a speed of 1.5 ft/s, determine the speed at which the platform is rising as a function of 
. Each link is pin-connected at its midpoint and end points and has a length of 4 ft.
vS = 2.67 sin2 ft/s
ft/svS = 1.500 cot ft/s
ft/svS = 1.500 tan ft/s
ft/svS = 2.67 cos ft/s
