Q4.) You are given a very hot sample of metal, and wish to know its temperature. You have a thermometer, but it only measures up to 200@C and the metal is hotter than that! You leave the metal in a room kept at 200 C. After 5 minutes it has cooled sufficiently that you can measure its temperature; it is 70@C. After another three minutes it is 40@C. What was the initial temperature of the metal?

Please answer the question as soon as possible. Calculate the moments of inertia I and I for a uniform disk of radius R and mass M. Take the z-axis to be perpendicular to the plane of the disk and passing through its center. If the disk rotates with angular velocity Ï‰ about the z-axis, what is the rotational kinetic energy? dm = da = adydz = ardrdÎ¸ x = rcosÎ¸ y = rsinÎ¸ z = 0

A beam of steel having square cross section of 20x20mm² having E = 200 GPa is subjected to an axial (P) load of 20 kN, Torsional (T) load of 60 Nm and Transverse (F) load of 0.60 kN as shown in Figure. Solve each load independently for both element A and B existing at the top and side surface of the beam respectively and determine: a) State of stress against each load condition for both element A and B b) Draw Mohr's Circle where applicable for each state of stress for both element A and B c) Determine the principal planes and the principal stresses, d) Draw the orientation of the Principal Stresses e) The stress components exerted on the element obtained by rotating the given element counterclockwise through 30 degrees.
