Lecture 8 Homework

Problem 1: Resultants using the parallelogram method
Determine the resulatant of each of the force systems given using the parallelogram method. (scale is indicated on the diagram)


Problem 2 : Resultants using the triangle method
Determine the resulatant of each of the force systems given using the triangle method. (scale is indicated on the diagram)


Problem 3: Orthagonal Components
Determine the orthagonal components of each of the forces.


Problem 4: Parallelogram Method

Determine why the force R is NOT the resultant of forces A and B.


Problem 5: Parallelogram Method
Given the truss with the forces and geometries indicated. Determine the resultant of the external forces.


Problem 6: Parallelogram Method
Given the forces indicated. Determine the resultant of each set.


Problem 7: Graphical Method Comparison
Given the forces indicated, determine the resultant using the triangle of forcs method; using the parallelogram method.
Note: Use a scale of 1"=50 K and start with any force at the point of concurrence. Then resolve the forces one at a time in any order.


Problem 8: Graphical Methods Review
Given the forces indicated, determine the resultant using any graphical method.
