A system uses 3 inputs for a logic circuit. Alarm X, will sound when input A is ON and input B is OFF; or when input B is ON and input C is OFF. Question: 1. Make an equation of the logic circuit, if the statement is simplified to: X = 1 if(A= 1 AND B = NOT 1) OR (B=1 AND C= NOT 1) 2. From these equations we can make logic gates. Fill in the logic gates below with the appropriate symbols:

Using the notation scheme for defining manipulator configurations, draw diagrams of the following robots. Label each joint in the diagram. (i) TVR:TR (ii) VROT:R

List and Describe the major specifications of the satellite power control unit (PCU)

a) A 380V, 7.5kW electric water pump of power factor 0.8 lagging and efficiency of 85% will be wired by an armoured XLPE insulated copper cable. The circuit will be run on cable tray with three other similar circuits at an ambient temperature of 40°C. MCCB will be used as the overcurrent protective device for the circuit. The estimated length of the circuit for the machine is 50m. i) Determine the minimum rating of MCCB for the circuit, available MCCB rating are 25A, 30A, 40A, 50A ii) Determine the minimum cable size of the circuit if the allowable voltage drop of the circuit is 1.5% of the nominal supply voltage?
