Q.
A person used force$\ (F)$, shown in figure move a load with constant velocity on give surface.
Identify the correct surface profile
A) [image:5_image95.emf]
B) [image:5_image96.emf]
C) [image:5_image97.emf]
D) [image:5_image98.emf]
Explanation
(a) The correct surface profile will be $(a)$, because slope of surface should change from one constant value (non-zero) in terms of sign because force is constant picewise.
