2 4. a) Deduce expressions and nature for the velocity, acceleration and jerk of the follower for a cam-follower mechanism when The follower moves with a simple harmonic motion. 8 b) The follower movement in a cam-follower mechanism with a translating flat-faced follower is given by $y(\theta) = 60(1-\cos \theta)$ mm, for $0 \leq \theta \leq 2\pi$. The limit on the contact stress requires that the minimum radius of curvature of the cam profile should not be less than 100 mm anywhere and during the rise period the driving effort not have an eccentricity more that 40 mm. Determine the minimum permissible base circle radius and the minimum required offset. What should be the minimum width of the follower if an allowance of 2 mm is desirable on both sides? 12 5. The exhaust valve of a gas engine opens 55° before outer dead centre and closes 15º after inner dead centre. A cam operates this valve. The minimum radius and lift of the cam are 4.0 cm and 1.5 cm respectively. Valve opens with constant acceleration and retardation, acceleration being twice the retardation. Period for closing the valve is the same as for opening. The follower returns with SHM. Draw the profile of the cam if the roller radius is 1.5 cm and offset is 1.0 cm to the right of centre of the cam. The cam rotates clockwise. 20 6. a) The gear B of the planetary gear train shown in Figure below is fixed. The arm A

Identify the following statements as true or false 1. An operand can be either only register, not memory or constant 2. Logical operations are such as NOT, AND, and OR are part of ALU 3. Datapath is collection of functional units that perform operations on data 4. A CPU uses a combination of all operations or a number of bits to communicate all other elements of a computer called Control Word 5. A single ISA (Instruction Set Architecture) cannot have multiple implementations 6. ARM is a kind of RISC microprocessor that is widely used in many of the mobile phones, PDA(Personal digital assistants), calculator and other small hand-held devices 7. Random Access Memory (RAM) is used to store information temporarily 8. In Big-Endian systems, the most significant byte of a multi-byte data item has the highest address, while the least significant byte has the lowest address. 9. Word addressable memory is faster than byte addressable 10. The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out stored program instructions.

[8 marks] This question investigates a variant of our standard TM model from class. (a) [6 marks] Consider a TM that, when it moves, left, automatically moves to the leftmost cell. We call this a TM a Left-Start TM. Describe how a standard TM can simulate a Left-Start TM. (Hint - Use the fact that you have the ability to mark cells as you move through the tape.) (b) [2 mark] What does this imply about the sets of languages recognized by both models and about the models themselves? [5 marks] This question allows you to explore variants of the computational models we've defined in class. Describe how Turing Machines and PDAs are different. How can you equate a Turing Machine to a PDA? (Hint What would a PDA need to be equivalent to a Turing Machine)

Title: Measurement and Instrumentation Hai, can anyone help me with this question on Measurement and Instrumentation? b) James uses an E-type thermocouple to measure the temperature in an oven. He has no ice bath but uses a reference bath exposed to the ambient air, which he measures with a thermometer to be 20°C. i. Derive the relationship between oven temperature and the voltage output. [3 Marks] ii. Determine the oven temperature if the output voltage is measured as 8.714mV. [3 Marks] iii. If the reference bath is replaced with ice (0°C), determine the output voltage of the thermocouple.
