Day 15 - Statics, Friction, Motion, Reverse Force

Component of Forces: Fx

Fx = F cosθ

Component of Forces: Fy

Fy = F sinθ

Resultant of Two or More Forces: Resultant Force

Resultant of Two or More Forces: Total Forces along Horizontal

Resultant of Two or More Forces: Total Forces along Vertical

Resultant of Two or More Forces: Angle

Conditions of Statics

Resultant and Angle of Two or More Forces: Cal Tech

Mode → Complex

R = F1<θ1 + F2<θ2 + F3<θ3

R = ans → r<θ

Note: If θ is negative, then just add 360

Friction: Friction Force

Belt Friction: Force Ratio

Rectilinear Motion: If speed is uniform

Rectilinear Motion: if speed varies

Use (+) a for rectilinear

Free Falling Body: If speed is uniform

Free Falling Body: If speed varies

Use (-) g
