Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

23. The programmer used three-point method to set up an accurate UF[3] on the part reference surface by sequentially recording points 1, 2, and 3 that are specified on the part reference surface for the three-points method in the robot system. If the programmer recorded three points used by the three-point method in the sequence of points 1, 3, 2 rather than point 1, 2, 3, then (a) the direction of x-axis is not changed (b) the direction of z-axis of UF[3] is changed (c) UF[3] setup is not accurate relative to the part reference surface (d) the origin of UF[3] is changed 24. The programmer preciously recorded all robot points P[n] for a robot task program. However, it is found that during the execution of the robot program, the robot TCP can't always precisely reach to each recorded point. Which of the following statements is correct: (a) The robot has poor accuracy (b) the robot has poor repeatability
