A human responds to a visual cue with a physical response. The transfer function that relates the output physical response, P(s), to the input visual command, V(s), is (s +0.5) G(s) V(s) (s + 2)(s +5) a) Evaluate the output response for a unit step input using the Laplace transform. b) Represent the transfer function in state-space. c) Using MATLAB (ss and step commands) simulate the system and obtain a plot of the step response.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Ahe-xe mixture containing a 0.75 mole fraction of helium is used for cooling electronics in an avionics application. at a temperature of 300 k and atmospheric pressure, calculate the mass fraction of helium and the mass density, molar concentration and molecular weight of the mixture. if the cooling capacity is 10 l, what is the mass of the coolant?

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
