A tractor of weight 15000 N crosses a single span bridge of weight 8000N and of length 21.0 m. The bridge apan supported half a meter from either end. The tractor front wheels take 1/3 of the total weight of the tractor, and the rear wheels are 3m behind the front wheels. Calculate the force on the bridge supports when the rear wheels are at the middle of the bridge span.



                                weight of tractor = w = 15000N
                                weight of bridge = wb = 8000N
                                length of bridge = lb = 21 m
                                length of tractor = l = 3m

To find:

                Force on bridge support =?


                The weight at the middle of bridge = weight of bridge + 2/3 weight of tractor

                                                                                     = 8000+ 2/3 x 15000

                                                                                     = 8000 + 10000 = 18000N

                                Its moments arm                  = 10m

                   Weight of tractor at point D       = 5000N

                     Its moment arm                              = 13m

                     Force at support                            A= F1

                     Its moment arm                               = 20m ans

                r1 + r2 + r3 =0

                18000 x 10 + 5000 x 13 – F1 x 20 = 0

                F1 x 20 = 245000

                F1 = 12250 N

Thus   F1 = 12.25 kN ans
