Answer:
2.1 rad(anticlockwise).
Explanation:
So, we are given the following data or parameters or information in the question above:
=> "The torsional stiffness of the spring support is k = 50 N m/rad. "
=> "If a concentrated torque of mag- nitude Ta = 500 Nm is applied in the center of the bar"
=> "L = 300 mm Assume a shear modu- lus G = 10 kN/mm2 and polar monnent of inertia J = 2000 mln"
Hence;
G × J = 10 kN/mm2 × 2000 mln = 20 Nm^2.
Also, L/2 = 300 mm /2 = 0.15 m (converted to metre).
==> 0.15/20 (V - w) + θ = 0.
==> 0.15/20 (V - w ) = -θ.
Where V = k = 50 N m/rad
w = 183.3 θ.
Therefore, w + Vθ = 500 Nm.
==> 183.3 + 50 θ = 500 Nm.
= 6.3
Anticlockwise,
θ = 2.1 rad.
<u>Explanation</u>
The Iron is incontact with the shirt. So, heat is transferred from the iron to the shirt because they are in contact.
Before the contact, there is temperature difference between the shirt and the iron. When they come into contact there must be exchange of heat energy, this happens until equilibrium state is reach.

True,According to Isaac Newton believes that Gravity is responsible for drawing attraction which is directly proportional to product of their masses but inversely proportional to the square of the distance between them.
Divide 10 by .05 and that is your answer
