The question as text
A student is investigating how the forces acting on a bridge vary as the position of a load on the bridge is changed. The bridge is modelled as shown in Fig. 2.1 with two newton-meters providing the support forces. T1 T2 s x m newton-meter newton-meter A Fig. 2.1 A load of mass m is placed at a distance x from support A. The readings of the newton-meters T1 and T2 are recorded for different values of x. It is suggested that T1, T2 and x are related by the equation T1 − T2 = mg(s − x) − mgx s where s is the separation of the newton-meters and g is the acceleration of free fall.
