Homework Help Overview

The discussion revolves around creating a free-body diagram for a Mercedes-Benz 300SL parked on an inclined road. The problem involves analyzing forces acting on the car due to gravity and friction on a slope of 15 degrees.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the representation of forces in the diagram, particularly questioning the labeling and direction of the gravitational force ("mg"). There is also an inquiry into the number of forces acting on the car and the clarity of the diagram.

Discussion Status

Some participants are attempting to clarify the forces represented in the diagram and are seeking to ensure accurate labeling and understanding of the components involved. There is an indication of productive dialogue regarding the identification of forces, though no consensus has been reached on the correct representation.

Contextual Notes

Participants note issues with the clarity of the diagram, including difficulties in enlarging it for better visibility and confusion over the correct representation of gravitational components (mg sin and mg cos).

Homework Statement


A Mercedes-Benz 300SL (m = 1700 kg) is parked on a road that rises 15 degrees above the horizontal. What are the magnitudes of (a) the normal force and (b) the static frictional force that the ground exerts on the tires? Important: Assume that the road is higher up to the right and lower down to the left.
Create the free-body diagram. Please use the blue vector to specify forces.

Right now I'm currently stuck with the vector highlighted in red. I just don't understand if it the angle that it is in or the length that is wrong.

The diagram appears to have two forces that are labeled "mg" (one red and the other blue). What type of force does "mg" represent? How many such forces act on the car?
 
I am not able to enlarge your diagram to see things clearly. You seem to have drawn four vectors. Please list them and describe them along with statements of the direction of each.
 
I added an extra vector. I was mistakenly adding the mg sin and mg cos
