joyland is going to open an alligator themed amusement park whose main attraction will be a huge mechanical alligator near the coffee shop. the jaws of the mechanical alligator will be actuated using a hydraulic cylinder; this hydraulic ram has to overcome the self-weight of the jaws by providing sufficient force. the upper jaw weighs 670lbf and lower jaw weighs 450lbf. each of these weights are considered to be acting upon their respective center of gravities i.e. points e and g respectively. the lower jaw makes an angle of 70ยบ with the negative x-axis measured in cw direction. cd=40in & bc=60in. each of the jaws has partial gear incorporated and they mesh as shown in the figure. assume any data if required. a) specify and indicate the number and types of links and joints utilized in this mechanism. b) calculate the mobility of the mechanical alligator. c) considering the jaws are stationary; conduct the static force analysis of the mechanical alligator and design the hydraulic cylinder with the necessary force that it should carry to sustain the mechanism d) if the lower jaw is to be designed such that it rotates at a constant clockwise angular velocity of 10rpm; then conduct the kinematic (position, velocity and acceleration) analysis of the mechanical alligator determine angular acceleration of upper jaw and linear acceleration of hydraulic cylinder (ram). e) also construct the mechanism in virtual environment and perform the kinematic analysis in any mechanism analysis software (mechanalyzer/ps motion/gim/solidworks). f) compare the analytical/graphical & simulation results.
