A double collar C is pin-connected together such that one collar slides over a fixed rod and the other slide over a rotating rod (refer to Figure #2). The geometry of the fixed rod for a short distance can be defined by a lemniscate. Y = 4 cos2 theta The unit for r is meter. Rod OA is rotating at a constant rate of d Theta = 6 rad/s. At the instant Theta = 0 as shown. (1) Determine the double collar?s radial and transverse components of velocity. (2) Determine the double collar?s acceleration

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.
