T1=10 Nm step input torque is applied to the mechanical system in the figure below, whose transformation ratio is given as n=1:10, at the time of t=0. Find the velocity and moment of the first and second sides. (System Parameters: B1=0.02 Nm/rad/s, B2=0.5 Nm/ rad/s, J1=0.2 kgm^2, J2=5 kgm^2)

In a moving coil instrument, the coil has a length of 5 cm, a width of 4 cm and 80 turns. The magnetic flux, density in the air gap is 0.1 Wb/m², the hair spring provides a controlling torque of 0.5 × 10² Nm/ degree deflection of the coil. What current will be required to give a deflection of 600?
