Document Content and Description Below

A uniform plane lamina is in the shape of an isosceles trapezium ABCDEF, as shown shaded in Figure 1. • BCEF is a square • AB = CD = a • BC = 3a (a) Show that the distance of the centre of... mass of the lamina from AD is 11 8 a (5) The mass of the lamina is M The lamina is suspended by two light vertical strings, one attached to the lamina at A and the other attached to the lamina at F The lamina hangs freely in equilibrium, with BF horizontal. (b) Find, in terms of M and g, the tension in the string attached at A (2) _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ ________________________________________________________ [Show More]
