Question

scenes M1.1 Normal, shear, and bearing stress For the pin connection shown, Pin diameter = 16 mm determine the normal stress acting on the gross area, the normal stress acting on the net plate area, the shear stress in the pin, and the bearing stress in the 45 kN steel plate at the pin. (Stress units MPa) Pin 70 mm Gusset Steel plate Ogross 10 mm thickness Onet Column T pin Ob

Answer 1

thank you and please do rate.

for the Thickness of = 16mm given Connection Sted plate = 10mm width of steel plate 70 mm Pin diameter Load coming on to the Steu plate 45 KN (Tensile) normal stress acting on the gross area is Tg Load 64.286 N/mm Gross area 90(10) Irg = 64.286 N/mm now 45 KN normal stress acting on ner area net area of plate = (B-d)xt (70-16)+10 540mm Theta Load 45 KN 83.333 N/mm ner Area 540 mm Thet= 83.333 n N/mm S shear stress in the pun pun प 4 Load 45KN 223.812 N shear area 201.062 mm pun= 223.812 N/mm2 Bearing stress in the Sted plate at the pain Bearing area= Diamereix thickness of plate 16mm x 10mm 160mm Tb Load 45 KN 281.25 mm Area 160mm To = 281.25 N/mm
