1.	The outer side of a circular track of radius 200 m is raised to make an angle of 15^@ with the horizontal Using the data provided in this case,determine the maximum permissible speed to avoid skidding. (Given mu_s = 0.25).
Answer» Solution :`R = 200 m, theta = 15^@, mu_s = 0.25` `v_max = SQRT Rg(TAN theta + mu_s)/1- mu_s tan theta = sqrt 200 XX 9.8(tan 15^@ + 0.25/1-0.25 xx tan 15^@= 32.98 MS^(-1)`
