Please choose the false answer(s) from the following statements related to CAD! a. It can be used for programming of robots, which may operate in a workcell arrangement, selecting and positioning tools and workpieces for NC machines. b. It is a technology which uses computer system to assist in the creation, modification, analysis and optimization of a design. c. Geometry can be used as a basis for other functions in CAE and CAM, saving time and reducing errors caused by redefining the geometry of design. d. Basic role of CAD is to define the geometry of design (computer aided drafting, and geometric modelling are the most important component of CAD).

a. Currently, you serve as a robotic engineer by a company, and your boss want you to design a robot in spatial space to satisfy the following conditions: i. Max reachable distance of the robot is 1 meter. ii. Only using revolute joints, connecting links and rigid load bearing links (the length of link is 0.5m). iii. The degree of freedom (Dof) of the robot is 2. What is your design, how many joints and links will you use? b. The payload of your design is 10 kg (each load bearing link can hold 5 kg, 5 kg+5 kg=10kg, the weight and payload of the connecting links will be ignored), but your boss wants your designed robots to handle 20 kg payload. How will you update your current design, and how many joints and links will you use in the new design? What is the Dof of the new designed robot.

a. What is the ideal mechanical advantage of this system? The inclined plane dimensions are 7.2 meters length and 1.8 meters height.b. What effort force is required to move the 600N create? c. In practice, you need to supply an effort force of 75 N to lift the crate. What is the efficiency?d. How could you redesign this compound machine so that the effort force needed was 50 N in practice? Assume the efficiency is your response from part C no matter what changes you make. Be specific with the changes you propose (if you add pulleys state how many, if you change the inclined plane dimensions state the new dimensions, etc.).
