Web0.26 = tan θ. Take the inverse to find θ. θ = tan − 1 ( 0.26) Hence, the current slope of the mountain has an angle θ = 14.57 °. However, the year after, the mountain experienced an eruption that increased the coefficient of friction by 0.34. Thus, the new coefficient of friction is. µ µ n e w = 0.26 + 0.34. WebThe static frictional force is self-regulating, i.e. static friction will at all times be equivalent and opposite to the force applied. R is the reaction force because of the weight W. The external force is F, and f r is the friction. F = -f r when no motion takes place. Watch the video to understand the nuances of static friction 22,322
