Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing. 

Question

Q1)
A hollow transmission shaft, having an inside diameter 0.6 times the outside diameter,
is made of plain carbon steel 40C8 (0,= 380 N/mm2), and the factor of safety is 3.
A belt pulley, 1000 mm in diameter, is mounted on the shaft,
which overhangs the left-hand bearing by 250 mm. The belts
are vertical and transmit power to the machine shaft below the
pulley. The tension on the tight and slack sides of the belt are
3 kN and 1 kN respectively, while the weight of the pulley is
500 N. The angle of the wrap of the belt on the pulley is 180°
. Calculate the outside and inside diameters of the shaft.
