A punching press pierces 40 holes per minute in a plate using 10 kN-m of energy per hole during each revolution. Each piercing takes 35 per cent of the time needed to make one revolution. The punch receives power through a gear reduction unit which in turn is by a motor driven belt pulley 770 mm diameter and turning at 250 r.p.m. Find the power of the electric motor if overall efficiency of the transmission unit is 88 per cent. Design a cast iron flywheel to be used with the punching machine for a coefficient of steadiness of 5, if the space considerations limit the maximum diameter to 1.3 m.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

Question

Can you help me solve this problem?

A punching press pierces 40 holes per minute in a
plate using 10 kN-m of energy_per hole during each
revolution. Each piercing takes 35 per cent of the time
needed to make one revolution. The punch receives
power through a gear reduction unit which in turn is
fed by a motor driven belt pulley 770 mm diameter
and turning at 250 r.p.m. Find the power of the electric
motor if overall efficiency of the transmission unit is 88
per cent. Design a cast iron flywheel to be used with
the punching machine for a coefficient of steadiness
of 5, if the space considerations limit the maximum
diameter to 1.3 m.
Allowable shear stress in the shaft material = 50 MPa
Allowable tensile stress for cast iron = 4 MPa
Density of cast iron = 7200 kg/m3
