Question 1. (Conceptual questions) I. The wind turbine shown in Figure 1(a) below is rotating with a constant angular velocity of magnitude wo in the clockwise direction as shown in the figure. Assume the distance from point P (i.e. blade tip) to the rotor centre to be L. For this wind turbine: (a) Obtain the velocity and acceleration of point P which is located at the tip [8 marks] of the blade in terms of L and wo, in a refernce frame B attached to the blade (define the reference frame yourself). [5 marks] (b) Draw the velocity and acceleration components of Point P. How do the directions of the components change as the turbine blade rotates? Suggested time: 15 minutes. P @o Figure 1(a)
