Unformatted text preview: ∑ = ⎯→ ⎯ + x F800N+N sin60+ V cos60=0 ∑ = y F V sin 60 – N cos 60 = 0 Solving for the 2 equations: N =692.8 N V= 400 N Average stresses: In this case, the sectioned area has a thickness and depth of 40 mm and 40 mm/sin 60= 46.19 mm respectively. Thus, the average normal stress is: ( ) ( ) KPa m m N A N 375 04619 . 04 . 8 . 692 = = = σ And the average shear stress is: ( ) ( ) KPa m m N A V avg 217 04619 . 04 . 400 = = = τ Problem 6....
