Direction cosines statics
WebQuestion: Q3: Prove that the direction cosines satisfy the condition cos? a + cos² B + cos² y = 1. (Hint: See, e.g., Section 2.5 of Hibbeler Statics 14th Ed.) Q4: Example 2.14 of Hibbeler Statics 14th Ed.: Determine the components of the force F along the u and v axes. (Hint: See, e.g., Example 2.2 of Hibbeler Statics 14th Ed.) WebDirection cosines are also used to represent a force vector. Mathematically, they are rectangular components of the given unit vector in such a way that F== + +FF F Fλ cos cos cosθxij kθθyz(5) where cos , cos and cosθxθθyzare direction cosines, while , and θxθθyzare direction angles (Figure 2).
