• Understand the concept of Force as a vector.• Understand separating a vector into
components.• Apply this concept to analyzing sums of Forces.• Determine the load in structural elements.• Understand the concept of a “Factor of Safety”.
• Draw a sketch of the Forces• Write each force in terms of i and j components (components
perpendicular to each other can be treated separately) • Sum of i and j components = zero (Newton’s 1st Law)• Solve two equations, two unknowns• Find tension force in cable• Calculate safety factor
