Question

A 400 N force is exerted at an angle of 60° to move a railroad car
Eastward along a railroad track. A top view of the situation is depicted
in the diagram below.
Calculate the vertical (southward) and horizontal (eastward) components of
force applied on the car.​

Answer 1

Answer:

this is the answer

Explanation:

pressure=force/ area = 400/60=0.15N is answer

Answer 2

Given:-

• force= 400N
• at angle 60°

To Find:-

• Southward and northward components of force.

Solution:-

Southward component will be written as Fcos60° and eastward component can be written as Fsin60°

Putting values:-

southward component= 400 x cos60°= 400 x 1/2=200N

eastward component = 400 x sin60° = 400 x √3/2= 200√3

Additional informatio

• cos 30° =√3/2
• sin30°=1/2
• sin15°=$\LARGE \frac{√3-1}{2√2}$

• cos15°=$\LARGE \frac{√3+1}{2√2}$
• cos90°=0
• sin90°=1
