Question 6
A block made of perfectly plastic material with a yield stress of 260 MPa in simple tension has the diameter 200 mm × 100 mm × 150 mm (b × h × w) at one instant during plane strain forging. Assuming there is sticking friction, the peak pressure will be
Question 7
In a single pass rolling operation, a 20 mm thick plate with a plate width of 100 mm, is reduced to 18 mm. the roller radius is 250 mm and rotational speed is 30 rpm. The average flow stress for the plate material is 300 MPa. The power required for the rolling operation in kW is closest to
Question 8
A round disk of 150 mm diameter is to be blanked from a strip of 3.2mm, half-hard cold rolled steel whose shear strength = 310 MPa.(for half hard cold rolled steel, clearance= 0.075 x thickness).Calculate the blanking force.
Question 9
The time taken to drill a hole through a 25 mm thick plate with the drill rotating at 300 rpm and moving at a feed rate of 0.25 mm/revolution is
Question 10
Two 8 mm thick steel plates are placed 5 mm apart and welded by a butt joint. Welding is carried out at 20 V. Heat transfer efficiency is 0.80. If the heat required to melt steel is 10 J/mm3 and melting efficiency is 0.625. The weld current is 200 A. The welding speed (in mm/s) is ___________.
