Answer:
20/54
Step-by-step explanation:
Forces in direction x:
fx1 = 100 * cos (50) = 64.28
fx2 = 50 * cos (160) = - 46.99
The resultant is:
fx = fx1 + fx2 = 17.29
Forces in direction y:
fy1 = 100 * sine (50) = 76.60
fy2 = 50 * sine (160) = 17.10
The resultant is:
fy = fy1 + fy2 = 93.70
The magnitude of the resulting force is:
f = root (fx ^ 2 + fy ^ 2)
f = root ((17.29) ^ 2 + (93.70) ^ 2)
f = 95.28
The angle is:
theta = atan (fy / fx)
theta = atan (93.70 / 17.29)
theta = 79.55 degrees
Answer:
The direction and magnitude of the resultant force are:
f = 95.28 pounds at theta = 79.55 degrees
1. A real world scenario could look something like this:
A ladder is resting against a straight wall. The distance from the top of the ladder to the bottom of the wall is 8m, while the distance from the base of the wall to the foot of the ladder is 6m. Find the length of the ladder.
2.That is the diagram for the real life example
3. Use pythagoras theorem to solve it
6^2+8^2=x^2
100=x^2
x=10
So the ladder is 10 m
