In the drawing, arm A is being driven back and forth in the direction of the arrows. It is connected to a gripper by way of an adjustable link L, two horizontal bars and two vertical bars. Screw B is a shoulder screw secured to arm A, but allows the horizontal bar to pivot around it. If the shoulder screw B was lowered towards the end of arm A, and the stroke of arm A remained the same, the stroke of the gripper would:

q4 part b provide handwrittten answer
Please show the FBD clearly and solve for the force asked. Thanks
The primary unbalanced force is maximum when the angle of inclination of the crank with the line of stroke is 90° and 180° 180° and 360° 0° and 90° 0° and 180°
Find the undamped position too pls
REACTION FOR POINT A PLEASE
Identify the links and joints. Then solve for the freedom of degrees.
The secondary unbalanced force is maximum times in one revolution of the crank.

1. Determine the horizontal and vertical stroke af a slider D and F when crank AB rotates 30 degrens sideways. AB-20, BC-25, CD-30, 8D-50, CF-45cm. Draw in appropriate scale E A B G
3. A plumber, kneeling on the floor next to the sink, reached for the monkey wrench in his toolbox, pushing around a few other tools before grasping the wrench and picking it up. He then moved it to the pipe beneath the sink, positioned it into the pipe fitting, and turned the fitting one-third of a rotation to loosen it. Once loose, he put down the wrench and continued turning by hand. Four rotations were required before the fitting was free of the mating pipe threads, during which he had to grasp and regrasp the fitting ten times due to the limited rotation ability of his own wrist. Write a list of the therbligs that comprise this motion sequence and label each basic motion with a brief description.
