Question
As shown in Figure 3, it is required to design an automatic bottle filling station. The process sequence is below. 1. Start and Stop pushbuttons are used to start and stop the process respectively. 2. Start is pressed Conveyor starts moving until the Proximity Sensor is ON. 3. Then the solenoid valve is open for 5 seconds. After 5s Conveyor should start moving (use a timer). 4. The above process should continue unto 10 bottles. 5. Stop the process whenever a stop push-button pressed. Explain the logic sequence in steps or by a flow chart. Write the PIC C code with the comment on each instruction. Draw an interfacing diagram or block diagram of all required components for the above objectives. Assume all suitable data with an explanation.

Question
6/64 The jack shown is designed to lift small unit-body automobiles. The screw is threaded into the collar pivoting at B, and the shaft rotates in a ball thrust bearing at A. The thread has a mean diameter of 10 mm and a lead (advance per revolution) of 2 mm. The coefficient of friction of the threads is 0.20. Determine the force P normal to the handle at D required (a) to raise a 500-kg mass from the position shown and (b) to lower the load from the same position. Neglect friction in the pivot and bearing at A.
