First Grade- Spring Semester

Force Couple

Instructor: Rasha Alkabbanie

Lecture Outlines and Objectives

In this lecture, information about the following topics will presented:

• Concept of the Force Couple

• Solving Problem 1/L4

Lesson Objectives:

• To be able to find the resultant force and the couple of many forces

• Solving Problem 2/L4

• Solving Problem 3/L4

The Resultant Force

= 80.cos(30)

= 80.sin(30)

= 60.sin(45)

= 60.cos(45)

= 2.4 .cos(20)

= 2.4 .sin(30)

= 1.5 .sin(20)

= 1.5 .cos(20)

= 3.6 .sin(20)

= 3.6 .cos(20)
