The coefficient of static friction between a wooden block of mass 0.5 kg and a vertical rough wall is 0.2. What is the minimum horizontal force (in newtons) that must be applied to the block to keep it adhered to the wall? (take g = 10 m/s²) 5 July 2025 Read More »
An inclined plane is bent in such a way that the vertical cross-section is given by 𝑦 = 𝑥²/4, where y is in vertical and x in horizontal direction. If the upper surface of this curved plane is rough with coefficient of friction μ = 0.5, determine the greatest vertical height (in cm) at which the block can remain at rest without sliding down the surface. 4 July 2025 Read More »
