28 CHAPTER 1: Introduction to Statics 1.52 Given that P = 120 lb and Q = 130 lb, find the rectanguan representation of P + Q. a r 1.53 Knowing that P 90 lb and that the resultant of P and O Jies in the pos tive x-direction, determine Q and the magnitude of the resultant 决1.54 lf R is the resultant of the forces P and Q, find P and Q. 12 Figure P1.52, P1.53 25° 55° 12 ft 0- Figure P1.54 Figure P1.55 1.55 The force R is the resultant of P and Q. Determine Q and the angle 1.56 The vertical post is secured by three cables. The cables are pre-tensions so that the resultant of the cable forces F. 0, and P is directed along the z-axis I Need help on 1.53 and 1.54
