WebApr 14, 2024 · where the subscript 1 refers to quantities in the upwind surface and \(A_1\), \(A_2\) are constant parameters. In this model the value of the mean vertical velocity W at the top of the IBL is assumed to be positive and it is modelled to be proportional to \(\delta _i/x\) or \(\text {d}\delta _i/\text {d}x\) using the continuity equation. They further extended … WebFeb 9, 2024 · Question 2. Coefficient of sliding friction on a body is 0.5 and the normal force applied is 200 N. Find the force due to sliding friction. Solution: N = 200 N. μ = 0.5. F= μ × N. F = 0.5 × 200 N = 100 N. So, sliding friction applied on body is 100N. Question 3. What does sliding friction depend on? Answer:
