True/False.Explain: âz can be expressed in terms of ấ¡ and âg (i.e., âz is a linear combination of â1 and âs).Hence the vector equation produceslinearly independent scalar equations.1.33 A vector revolution in geometry. (Chapter 2)The relatively new invention of vectors (Gibbs z 1900 AD) has revolutionized Euclidean geometry(Euclid z 300 BC).

In the tree diagrammed here, a force of 800 N is exerted at the tip of the limb (equivalent to the weight of "800 apples). The limb is circular in cross-section and 2 m long with a tip radius of 3 cm a base radius of 10 cm. The radius increases linearly from the tip to the base. Plot the tensile stress at the top of the limb along its length. Where along the length would you expect the limb to break? M. X. Lo Y
