Plate draw the 2D skect of the figure in autocad and give the dimension.

Calculate the mobility of the kinematic chain please

Define and show on the figure the necessary vectors and their angles for second mechanism and construct the corresponding vector-loop equation(s). please draw the vectors and angles and visually show them on mechanism you can name the angles theta1, theta2 etc. it should be looking exactly like the example( first mechanism).

Version B We have worked with Ferris Wheels above ground, but what if a portion of it went underground and traveled in a clockwise direction? Details; The Ferris Wheel has a diameter of 80 ft The Ferris Wheel center is 20 feet below the ground The Ferris Wheel rotates in a clockwise direction The rider enters on ground level on the right side of the wheel. It takes 1 minute for 1 ½ rotations. Your task: Determine the angular speed. Develop an equation for the height of the rider while on the ride. Calculate the rider's total distance traveled from the moment they get on at ground level on the right to the other point on ground level on the left where they get off.

Please help me with this Kinematics problem. This is for kinematics & dynamics of machines. Thank you.

Use rotation about the current frame to calculate the transformation matrix for a rotation of 90° about yo axis and then 90° about zo axis.

please show the steps of what they do here i do not understand thanks
