4-33. A 60-in. television, with a mass of 3.11 slugs, is loaded onto a truck using a ramp as shown in Fig. P4.33. A vector dia- gram showing the corresponding balance of forces acting on the TV is also shown in this figure. (a) Given that h = 3 ft and b= 10 ft, determine the angle 0. (b) Using the positive x-y coordinate 4- system shown in the figure, write the friction force F, the normal force N, and the weight W in rectangular form (i.e., in terms of unit vectors i and ĵ). Note: The weight W in pounds (lbf) is given by W = mg, where g = 32.2 ft/s2 is the acceleration due to gravity and m is the mass in slugs. (c) Substitute your results from part (b) into the equilibrium equation F+ N + W = 0 and determine the values of F and N (in lbf). FE %3D %3D %3D
