Question

onent of reaction (R) perpendicular to the plane of contact is called normal react
onent of reaction (R) parallel to the plane of contact is called frictional force (f).
resultant of frictional force (f) and normal reaction (N) is equal to the Reaction fo
ude of reaction force is given by
R= N? + f?​

Answer 1

Answer:

R²=N²+f²

R=√N²+f² is the resultant of frictional force and normal reaction
