in viscous damping free vibration response what has the most
powerful effect among m, c, k and initial condition? please write
the reason.

In viscous damping free vibration when we increase the damping
the deflection will decrease exponentially up to critical damping
beyond that increase in damping increase the time to come to zero
deflection
when we change the spring constant by keeping all other
parameters constant deflection will vary parabolically (i.e.,
deflection always decreases with increasing spring constant)
the response of system by changing the mass has the effect same
as that of changing spring constant by increasing the mass the
deflection will always increase.
By changing the initial condition up to certain deflection the
response will be more but after a certain limit, the response will
decrease.
Q5. A monopolist has the cost function C(Q) = m*Q +k*Q2 where m
and k are parameters. It faces two types of consumers, A and B,
with the following demand curves for its product: PA =60–3*QA PB
=80–2*QB For (a)—(c) below, assume Assume m=30 and k=0.
(a) [4] What price will the monopolist charge under uniform
pricing?
(b) [4] What prices will the monopolist charge if it can price
discriminate?
(c) [4] How much higher is the monopolist’s profit in...
Water flows at 112°C through a steel pipe (k=90 W/m °C) which
has a 6 cm inside diameter and 8cm outside diameter. Such that, hi
=346 W/m2 °C and ho =6.0 W/m2 °C. Surrounding air temperature is
20°C. To reduce heat loss to the surroundings the pipe is covered
with an insulation insulation having the thickness of 4.0 mm and
k=0,5W/m°C . Calculate;
a. The heat loss by convection per unit length from
the bare pipe (before insulation).

A Styrofoam(k = 0.035 W/m-°C) box has outer dimensions of 250 mm
x 450 mm x 600 mm and is 3 cm thick. Initially, the box is filled
with 40kg of ice at 0°C, and the inner surface temperature of the
ice chest can always be taken to be 0°C. The heat transfer
coefficient between the outer surface of box and surrounding air at
35°C is 20 W/m2 -°C. (a) Determine how long it will take for the
