[#426] Crushing resistance required to crush the rivet per pitch length is
Correct Answer
(C) $${ ext{ndt}}{sigma _{ ext{c}}}$$
[#427] Tearing resistance required to tear off the plate per pitch length is (where p = Pitch of rivets, d = Dia. of rivet hole and $${sigma _{ ext{t}}}$$ = Permissible tensile stress for plate material)
Correct Answer
(D) $$left( {{ ext{p}} - { ext{d}}}
ight){ ext{t}}{sigma _{ ext{t}}}$$
[#428] Which of the following welded joint is designed for shear strength?
Correct Answer
(B) Parallel fillet welded joint
[#429] Fibrous fracture occurs in
Correct Answer

[#430] The ratio of belt tensions $$frac{{{{ ext{p}}_1}}}{{{{ ext{p}}_2}}}$$ considering centrifugal force in flat belt is given by where, m = mass of belt per meter (kg/m) v = belt velocity (m/s) f = coefficient of friction $$alpha $$ = angle of wrap (radians)
Correct Answer
(A) $$frac{{{{ ext{p}}_1} - { ext{m}}{{ ext{v}}^2}}}{{{{ ext{p}}_2} - { ext{m}}{{ ext{v}}^2}}} = {{ ext{e}}^{{ ext{f}}alpha }}$$
