A position vector is defined as having a length equal to your height in inches (or centimeters). The tangent of its angle is defined as your weight in pounds (or kilograms) divided by your age in years. Calculate the data for this vector and:
a. Draw the position vector to scale on cartesian axes.
b. Write an expression for the position vector using unit vector notation.
c. Write an expression for the position vector using complex number notation, in both polar and cartesian fonns
A roller cam is used to impart a periodic motion to the base of the spring-mass system shown in Fig. 4.41. If the coefficient of friction between the mass and the surface is µ find the response of the system using the principle of superposition. D..
A delivery vehicle carries a long sign on top, as in Fig. If the sign is very thin and the vehicle moves at 65 mi/h, estimate the force on the sign with no crosswind.

Prob. 8.46 The machine part ABC is supported by a frictionless hinge at B and a 10° wedge at C. Knowing that the coefficient of static friction is 0.20 at both surfaces of the wedge, determine (a) the force P required to move the wedge to the left..
You are asked to measure non-destructively the yield strength and tensile strength of an annealed 65-45-12 cast iron structural member. Fortunately, a small hardness indentation in this structural design will not impair its future usefulness, which i..
