Chapter 10, Problem 46A
The sketch shows a coin at the edge of a turntable. The weight of the coin is shown by the vector W. Two other forces act on the coin, the normal force and a
Expert Solution & Answer
To determine
To draw:The sketch of the force vectors for the normal force and a force of friction.
Answer to Problem 46A
The force vectors for the normal force and a force of friction as shown in Figure 1.
Explanation of Solution
Given:
The weight of the coin is
The given figure is shown below.
Formula used:
The normal force is the support force exerted upon an object that is contact with the surface.
The frictional force is the force generated by two surfaces that contacts and slide each other.
The weight of the coin is the vector W act vertically downward.
The normal force on the coin is the vector N act vertically upward.
The frictional force on the coin is the vector f act horizontally towards the center of the turntable. The frictional force prevents the coin from sliding off from the turntable.
Sketch the forces acting on the turn table as shown below.
Figure 1
Conclusion:
Thus, the force vectors for the normal force and a force of friction as shown in Figure 1.

The abstract should be a short paragraph that very briefly includes the experiment objective, method, result and conclusion. After skimming the abstract, the reader should be able to decide whether they want to keep reading your work. Both the format of the report and the error analysis are to be followed.
