g adjust the proportional, derivative, and integral gains to achieve a settling time of 3 s and meet the previous requirements: 1.2 second peak time, less than 20% overshoot, less than 10% steady-state error. If the peak time is too slow, increase the proportional gain. If the overshoot is too high, increase derivative gain. If making those changes causes too much steady state error, increase the integral gain. Can you find gains to meet all requirements

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

List 3 options on how to reduce knocking problens during engine process,

Steel balls 12 mm in diameter are annealed by heating to 1150 k and then slowly cooled to 400 k in an air att 325 k and h -20 w/m2 k. assume the properties of the steel to be k- 40 w/m k,p 7800 kg/m3, and cp 600 j/kg k. a. determine whether lumped system method can be used to analyze this problem and if so why" b. determine the time required for the cooling process. c. determine the total amount of heat lost from each ball to the ambient air
