2. A blanking die must be designed to blank the part outline shown in Figure below....
4. A blanking operation is performed on 5/32-in-thick cold-rolled steel (half hard). The part is circular with diameter 3.500 in. Determine: a) the appropriate punch and die sizes for this operation. b) the blanking force required, if the shear strength of the steel 40,000 lb/in2.
please draw and solve show every thing details “” Question 3 128 Marks 2 rectangular beam shown in the figure is subjected to a fluctuating axial force. It fluctuates between 5 kN and 15 kN keeping its direction. The beam is to be machined to the dimensions shown in the figure with a transvers hole of diameter d-14 mm/ Material of the beam is AISI 1040 CD steel (S-590 stress concentration factor as 2.2. K Pa, Sy 490 MPa). Take...
As shown in Figure 8, the structural member (beam) is 7m long, carries a 2 kN point load, a 1.2 kN/m uniformly distributed load and is supported at points A and B. The beam is constructed from two pieces of steel plate (2 at 80mm x 8mm) that are welded together with 3mm welds. Section properties for the beam are also listed. Given the support reactions as RAv 5.8 kN and RBv 2.2 kN, as well as the shear force...
Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...
