Chapter 6, Problem 39P

The Hip implant shown in Fig. P6.39 is subjected to a cyclic load during a fatigue test. The load applied to the hip implant is given by

$F\left(t\right)=200\sin \left(5\pi t\right)\text{+1000N}$

(a) Write down the amplitude, frequency (in Hz), period (in seconds), phase angle (in degrees), time shift (in seconds), and vertical shift (in N) of the load profile.

(b) Plot one cycle of the voltage $F\left(t\right)$, and indicate the earliest time when the force reaches its maximum value.
