Thread rolling is a kind of metal forming which is essentially a hot forging operation. Correct Answer False

Thread rolling is basically a kind of metal forming process which is essentially a cold forging operation. In this process, thread rolls are used which forced onto the component that prepared at the pitch diameter of the required thread. This method is widely used for manufacturing the bolts which combine with nut, and used for temporary joining.

Forging is a metal forming operation in which the metal is stretched to form the desired shape of a metal part.
An iron blast furnace produces hot metal containing 95% Fe. The iron ore charged into the furnace contains 95% Fe2O3 and the rest is gangue. Assume that all the iron in the ore goes to hot metal. The amount of iron ore (in kg) required for producing 1000 kg of hot metal is (Atomic weight of Fe = 56 g mol-1 and that of Fe2O3 = 160 g mol-1)
Consider the following multi-threaded code segment (in a mix of C and pseudocode), invoked by two processes P1 and P2, and each of the processes spawns two threads T1 and T2: int x = 0; // global Lock L1; // global main() { create a thread to execute foo(); // Thread T1 create a thread to execute foo(); // Thread T2 wait for the two threads to finish execution; print (x);} foo() { int y = 0; Acquire L1; x = x + 1; y = y + 1; Release L1; print (y); } Which of the following statement(s) is/are correct ?
Ram is playing with a thread and a brick of mass 2 Kg. He tied a thread one of its end with brick and another end with the roof. He holds the thread at 1 m below the roof and applying a force of 50 N. What is the tension that appeared in the upper part of the thread which is stick with the roof? Take (Tan 68° = 2.5; Cos 68° = 0.37; g = 10m/s2)
Steps are given to draw an ellipse by loop of the thread method. Arrange the steps. i. Check whether the length of the thread is enough to touch the end of minor axis. ii. Draw two axes AB and CD intersecting at O. Locate the foci F1 and F2. iii. Move the pencil around the foci, maintaining an even tension in the thread throughout and obtain the ellipse. iv. Insert a pin at each focus-point and tie a piece of thread in the form of a loop around the pins.
