Atorque of magnitude t = 11 kn·m is applied to the end of a tank containing compressed air under a pressure of 8 mpa. knowing that the tank has a 180-mm inner diameter and a 12-mm wall thickness, determine the maximum normal stress and the maximum shearing stress in the tank. (round the final answers to one decimal place.)

Max Normal Stress,

Max Shear Stress,

Solution:

As per the question:

Torque, T = 11 kN.m = 11000 Nm

The inner diameter of the tank,

Thickness of the tank, t = 12 mm = 0.012 m

Pressure, P = 8 MPa =

Now,

Inner radius of the tank,

Outer radius of the tank,

Now,

To calculate the polar moment of inertia, J:

Now,

To calculate the shear stress at the surface end:

Now,

To calculate the stress at the outer end:

Now,

To calculate the value of the shear stress,

The resultant stress,

The overall resultant of all the stresses (all in MPa):

Now,

Max stress,

Minimum stress,

Now,

Maximum shear stress,

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
