Please Solve and Give Detail. Thank you.
For a four-bar mechanism, the link lengths in inches and the value of the angle 02 are as follows: Link 1-5, Link 2-3, Link 3-8, Link 4-9, θ. = 45 degrees. Link l is the ground and link 2 is the driving link. (a) Is this a crank-rocker, double rocker, double crank or triple rocker mechanism? Justify your answer. [5 points] (b) Find the angles 0.04 and transmission angle when θ2 45 degrees...

P4.2: The four-bar mechanism in Figure P4.2 has the link lengths: LAB = 4", LED = 24", Loc = 14", LA = 30". The location of COM is as follows: LAG = 2.120"; LEG2 = 11.863"; LDG = 6.722". The crank 1 rotates counterclockwise with the angular displacement 8. = 27t-t [rad), angular velocity 0. = , = 21 [rad/s], and angular accelera- tion &= 7= 0 [rad/s). The mass and moment of inertia relative to each link's COM are...
Design a 4-bar linkage that can put the coupler link AB in the three positions shown in the figure below. The length of AB is 1.25 cm. The numbers beside A1, A2 and A3 are the coordinates of pin A in the three precision positions. You will probably find it helpful to scale the drawing to a more convenient size to work on. Submit your drawing of the designed mechanism (showing it drawn clearly in all three positions as well...
