Part A Express your answers using two significant figures. Enter your answers numerically separated by a comma. FA, FB = 2900,13200 N FA, FB = 2900,13200 N FA, FB = 2900,13200 N 2900,13200 Part A Calculate FA and FB for the beam shown in the figure The downward forces represent the weights of machinery on the beam. Assume the beam is uniform and has a mass of 270kg . Express your answers using two significant figures. Enter your answers numerically separated by a comma.Explanation / Answer
From the right.
2200 x 1 = 2200 Nm
3100 x 4 = 12400 Nm
4300 x 8 = 34,400 Nm
Total Torque, T = 49,000Nm torque on right support.
Force = 49,000 Nm / 10m = 4900N on left support.
From the left.
4300 x 2 = 8600N/m.
3100 x 6 = 18,600N.m
2200 x 9 = 19,800N.
Total torque, T = 47,000 Nm torque on left support.
Force, F = 47,000/10 = 4700N on right support.
The beam adds (1/2 * 270 x 9.8) = 1323 N on each support.
4700 + 1323 = 6,023 N right (FB).
4900 + 1323 = 6,223 N left. (FA).
