Ray HW Prob 13 RAX (pinned) F1 = Uniform load of 250#/LF %3D 30ft RB 75ft RA RB FBD of Moments around Rb Step 1: Draw the forces (and their distance from Rb) that create a moment around Rb in the FBD above Step 2: To Solve for RAx, sum moments about RB: CW Moment = CCW Moment CW Moment (+) Mag CCW Moment (-) Mag Force Dist. Moment Force Dist. Moment Sum CWM: Sum CCWM: Using Force * Distance = Moment, Solve for the unknown Force: RA RB FBD of Moments around Ra Step 3: Draw the forces (and their distances from Ra) that create a moment around Ra in the FBD Step 4: To Solve for RBx, sum moments about RA: CW Moment = CCW Moment CW Moment (+) Mag CCW Moment (-) Dist. Moment Force Mag Moment Force Dist. Sum CWM: Sum CCWM: To Check your answer, Sum Forces in the x direction = 0 To find Ray sum forces in y direction Finally, combine the x and y forces at the pinned connection to determine the reaction at the pinned connection and use trigonometry to determine the direction of the reaction: ans: Rax = 23.438 kps, RBx =23.438 kps, Ray = 18.75 kps, RA = 30.015 kps @ 39 deg %3D %3D %3D 83 11
