This is an example of an undamped forced oscillation where the phenomenon of beats occurs. find the solution of the initial value problem: x" + 7.84x = 2 cos(3), x(0) = x' (o) = 0 x(t) = graph the solution to confirm the phenomenon of beats. note that you may have to use a large window in order to see more than one beat. what is the length of each beat? length = ! would you be able to explain why the beats phenomenon occurs for this particular example?

Alow cost, low earth orbit (leo) satellite is to be fabricated at a university, for subsequent launch by rocket. what are the constraints and objectives for selection of a material suitable for the satellite bus (i.e. the structure)? explain each in brief. (15 marks) b)suggest sources of data which could support the selection of materials for applications in space. (5 marks) c) set weights for the objectives listed in (2a) using the digital logic method. (5 marks)
