QI: Determine the percentage increase in efficiency of an Atkinson cycle in comparison with the otto cycle for a compression ratio of 8.5. The pressure and
temperature of air at the beginning of compression are 1 bar and 27 °C
respectively. The peak pressure is 45 bar for both cycles.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information
