. 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

Fluids at rest possess no flow energy. a)- true b)- false

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
