Given that mass m = 25 kg , Normal Force N = 170 N  

   From Normal Forces F sin θ +N = W

                                     F sin θ + N = m g

                                F sin 26 0 + 170 N = 25 kg * 9.8m/s2

                                Fsin 26 0 + 170 N   = 245 N

                                   Fsin 26 0 = 245 N - 170 N

                                                    = 75 N

                                         F = 75 N / sin 26

                                               = 75 / 0.438

                                                  =171.08 N
