Question

This is a True or false question that has been bothersome please help

Question # 1
Check and state in your answer booklet which of the following statements is False and which is
True.
(1) The plastic region of the stress-strain curve for a metal is characterized by a propo.
relationship between stress and strain.
(2) A steel with 1.0 % carbon is known as high carbon steel.
(3) In flat strip rolling process, the entry thickness of the sheet is greater than the exit thickness.
(4) A fusion weld is a weld in which the metal surfaces have been plastically deformed to cause
nal
coalescence.
(5) In shielded metal arc welding (SMAW) process, the coating melts forming gases that protect
the welded joint.
(6) Resistance welding processes make use of the heat generated by electrical resistance to
achieve fusion of the two parts to be joined; no pressure is used in this process.
(7) Increasing cutting speed reduces flank wear of the tool.
(8) Centrifugal casting method is suitable for producing large diameter tubes.
(9) Surface turning process is performed on a shaper.
(10) Cold working of metals increase strength and reduce ductility of metal.
