The diagram shows a finished engineered component machined from a square piece of aluminium with holes drilled through it. The drilled holes have the shape of a cylinder.
Diagram not to scale and all dimensions in mm
(a) Calculate the volume of the component before any holes are drilled.
In transmission system, noise process N(t) having powerdensity
S.(0) = [(P)/(P + w*)], where P >0 is a constant is mixed with a single A cos(1)
Determine
(a) the average signal-to-noise ratio
(b) the value of P such that SNR is maximum,
What is the effect of choosing this value of P?
The inductance of moving iron ammeter in micro henry is given by expression:
L=20+5θ-2θ2
Where θ is deflection in radians from the zero position. Determine the angular in radians for a current of 10A if the for a current of 5A is 300.Also determine the spring constant.
