SSC SSC JE Mechanical 2025 Mock Test Series (Paper 1 & Paper 2) Engineering Mechanics Equilibrium and Friction Friction
The correct relation between angle of static frictions (ϕs) and coefficient of static friction (μs) during impending motion of body can be stated as:
1
tan ϕs/μs
2
tan ϕs = μs
3
tan ϕs - μs
4
tan ϕs > μs
