Resolving parallel and perpendicular to the plane

In summary, parallel lines never intersect and have the same slope, while perpendicular lines intersect at a 90-degree angle and have slopes that are negative reciprocals of each other. To determine if two lines are parallel or perpendicular, you can compare their slopes. Parallel lines will never intersect, but perpendicular lines will. When resolving a line parallel to a given plane, you can find the point of intersection and draw a perpendicular line to the plane at that point. Resolving parallel and perpendicular lines is important in various fields, as it helps determine relationships and properties and solve problems in applications such as engineering, architecture, and physics.

A rectangular block of mass 50kg is held by a rope on a rough surface inclined at 0.6 radians.
Assume that the coefficient of static friction is 0.2, determine what force needs to be applied to the rope to keep the block from slipping.

I did this by resolving parallel and perpendicular to the plane and found the the force required is196 N. however, I'm not sure of this. can someone please work this out and see if my answer is right.

Thank you!

That's what I get.
 

1. What is the difference between parallel and perpendicular lines?

Parallel lines are lines that never intersect, meaning they have the same slope and will never cross. Perpendicular lines, on the other hand, intersect at a 90-degree angle and have slopes that are negative reciprocals of each other.

2. How can you determine if two lines are parallel or perpendicular?

To determine if two lines are parallel, you can compare their slopes. If the slopes are the same, the lines are parallel. To determine if two lines are perpendicular, you can calculate the slopes and check if they are negative reciprocals of each other.

3. Can parallel or perpendicular lines ever intersect?

No, parallel lines will never intersect, as they have the same slope and will continue on indefinitely without crossing. Perpendicular lines, however, will intersect at a 90-degree angle.

4. How do you resolve a line that is parallel to a given plane?

To resolve a line that is parallel to a given plane, you can find the point where the line intersects the plane, and then draw a line perpendicular to the plane at that point. This perpendicular line will be the resolved line.

5. What is the significance of resolving parallel and perpendicular lines?

Resolving parallel and perpendicular lines is important in geometry and other fields of science, as it allows us to determine the relationships and properties of different lines. This can help us solve problems and make predictions in various applications, such as engineering, architecture, and physics.
