the bending moment shall be determined by measuring the weight of the lamp (e.g. by means of a balance) at the tip of the bulb of the horizontally held lamp and multiplying this force by the distance between the tip of the bulb and the pivot line ,the pivot line shall lie at the bottom end of the cylindrical part or at the end of the contact pins ,it shall be supported by an upright held thin metal sheet or a similar means , u8 z2 t o3 P& |作者: bub02 时间: 2017-3-7 10:12
灯头到重心的长度乘以灯重量再乘以重力加速度 就是弯矩
