Answer:
(a) 2.5 ksi
(b) 0.1075 in
Explanation:
(a)
Making the subject then
where is the stress and
is the strain
Since strain is given as 0.025% of the length then strain is
Now substituting E for then
(b)
Stress, making A the subject then
where d is the diameter and subscripts o and i denote outer and inner respectively.
We know that where t is thickness
Now substituting
But the outer diameter is given as 2 in hence
As already mentioned,
Answer:
Force per unit plate area is 0.1344
Solution:
As per the question:
The spacing between each wall and the plate, d = 10 mm = 0.01 m
Absolute viscosity of the liquid,
Speed, v = 35 mm/s = 0.035 m/s
Now,
Suppose the drag force that exist between each wall and plate is F and F' respectively:
Net Drag Force = F' + F''
where
= shear stress
A = Cross - sectional Area
Therefore,
Net Drag Force, F =
Also
F =
where
= dynamic coefficient of viscosity
Pressure, P =
Therefore,
Answer:
the three part are mass, spring, damping
Explanation:
vibrating system consist of three elementary system namely
1) Mass - it is a rigid body due to which system experience vibration and kinetic energy due to vibration is directly proportional to velocity of the body.
2) Spring - the part that has elasticity and help to hold mass
3) Damping - this part considered to have zero mass and zero elasticity.
