when subjected to an applied torque, a circular shaft of length 600mm twist through an angle of 2°.if the shear modulus for the shaft material is 80GN/m^3. determine shear stresswhen subjected to an applied torque, a circular shaft of length 600mm twist through an angle of 2°.if the shear modulus for the shaft material is 80GN/m^3. determine shear stress
•At the center of the shaft and
•At radius of 200mm
• If the maximum shear stress in the shaft is 120NM/m^3, what will be the outer diameter

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?

A 110 kg machine is mounted on an elastic foundation of stiffness 2 x106 When operating at 150 rad, the machine is subject to a harmonic force of magnitude 1500 N. The steady-state amplitude of the machine is measured as 1.9 mm. What is the damping ratio of the foundation?
Determine the Jacobin matrix, strain-displacement, stress of four nodal rectangular element.
The coordinates are A(10, 10), B(20, 10), C(20, 20) and (10, 20). Take E = 210GPa, μ = 0.3.

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.


A rope pulls a 200 kg sleigh up a slope at incline angle θ=30 deg, through distance
d=20m. The sleigh and its contents have a total mass of 200kg. The snowy slope is so
slippery that we take it to be frictionless. How much work is done by each force
(Normal, gravitational, rope’s) acting on the sleigh?
