The coefficient of static friction between a block of mass 0.25 kg and a horizontal surface is 0.4. Find the horizontal force applied to it.
Given: μS = 0.4, m = 0.25 kg, g = 9.8 m/s2 To find: Force (FL) Formula: FL = μSN = μS(mg) Calculation: From formula, FL = 0.4 × 0.25 × 9.8 = 0.98 N The horizontal force applied...

A block of mass 40 kg resting on a horizontal surface just begins to slide when a horizontal force of 120 N is applied to it.
Given: FL = 120N, Fk = 80N, m = 40 kg, g = 9.8 m/s2 To find: i. Coefficient of static friction (μS) ii. Coefficient of kinetic friction (μk) Formulae: i. μs = \(\frac{F_L}{N}\) ii. μk = \(\frac{F_K}{N}\) Calculation: From formula (i) we get. N =...

A 20 kg metal block is placed on a horizontal surface. The block just begins to slide when horizontal force of 100 N is applied to it.
Given: m = 20 kg, FL = 100 N, μk = 0.4 To find: i. Coefficient of static friction (μS) ii. Minimum force required (Fk) Formulae: i. μs = \(\frac{F_L}{N}=\frac{F_L}{mg}\) ii. μS = \(\frac{F_K}{N}\) Calculation: From formula (i), μs = \(\frac{100}{20\times9.8}\) = 0.5102 From formula (ii), Fk = μkN...
