Answer 1

Note: From P:02 the given data 1 obserue that there are certain mismatching in details given. One inner circle length is given as Ikm ( semicircle). Considering the circumference 77: 1000 =) Y: 1000 .318.47m 3.14 But here the radius is given 159m Anywr: Angle of banking - 394. - 31 -2799 300 106 U=0.75, Inner radius = 159m, outer radicy : 119m. Mean sadius: 159 + 179 169m Maximum speed without slipping Conap I'll tano X90 | Rg (tane+M) 169X 10 (tan (30) +0.75 1 - (0.75% tan(30) 169 x 10 x(0-5774 +0.75) 1 - (0.75*0.5774) 169 X 10 X 132-74 1 - 0.43 305
