The motion of a bob of a pendulum can be descibed by O= -5 cos(2 t) - 2 sin(2 t) where ө e is the angle made by the bob and pendulum for time, t, in seconds. Write e in the form Rcos (2t-B) gives A 5.39cos (2t-2.76) E B 5.39cos(2t - 158.20°) C ( 5.39 cos(2 t+2.76) ​

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
