. LTI System An LTI system is defined by the differential equation y’’(t) +6y’(t) +5y(t) = x(t) + x’(t) (a) Find the transfer function H(s) for the LTI system (hint: use Laplace Transform)(b) Find the impulse response h(t)(c) If x(t) = ⅇ-3t·u(t), find y(t) by convolution

Which of the following ziegler nichols tuning methods the response of the controller to a step input should exhibit an s-shaped curve? a)-open loop mode b)-closed loop mode c)-both modes (open & closed) d)-none of the modes (open & closed)

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
