8. The solution of dy -y=1, dt which additionally satisfies yo dy = dt It=0 = 0 in the Laplace s-domain is 1 1 (A) (B) s(s+1)(S-1) s(S-1) 1 (C) (D) s(s+1) s-1 9. In Materials Requirement Planning, if the inventory holding cost is very high and the setup cost is zero, which one of the following lot sizing approaches should be used? (A) Base Stock Level (C) Economic Order Quantity (B) Lot-for-Lot (D) Fixed Period Quantity, for 2 periods 10. Let I=xy dydx. Then, I may also be expressed as (A) xdxdy x= (C) xydxdy y=0 x=0 (B) xy dxdy y=0Jx=y xdxdy y=0x=0 11. A bolt head has to be made at the end of a rod of diameter d = 12 mm by localized forging (upsetting) operation. The length of the unsupported portion of the rod is 40 mm. To avoid buckling of the rod, a closed forging operation has to be performed with a maximum die diameter of mm. 8.
