Machine Design Two helical springs of the same material and of equal circular cross-section, length and number of turns, but having radii 80 mm and 40 mm, kept concentrically (smaller radius spring within the larger radius spring), are compressed between two parallel planes with a load W. The inner spring will carry a load equal to 2W/3 W/9 W/2 8W/9 2W/3 W/9 W/2 8W/9 ANSWER DOWNLOAD EXAMIANS APP
Machine Design The ratio of driving tensions for flat belts, neglecting centrifugal tension, is (where T₁, and T₂ = Tensions on the tight and slack sides of belt respectively, μ = Coefficient of friction, between the belt and pulley, and θ = Angle of contact) T₁/T₂ = μθ T₁/T₂ =eμθ log (T₁/T₂) = μθ T₁/T₂ = log μθ T₁/T₂ = μθ T₁/T₂ =eμθ log (T₁/T₂) = μθ T₁/T₂ = log μθ ANSWER DOWNLOAD EXAMIANS APP
