Figure 1.60 shows a five-link suspension that is sometimes used in off-road vehicle design. Each angle of the wheel hub can be precisely tuned, although tuning is a finicky and time-consuming affair. How many degrees of freedom does this suspension have? Sketch the suspension and draw an appropriate set of coordinates defining the degrees of freedom. Can the wheel hub move up and down in the required fashion?
