PROPOSED EXERCISE 23.2 - Crank OA rotates at a constant speed of 180 rpm and controls rocker arm CBD through roller A, which moves in the rocker arm slot. For the position shown in the figure, determine: (a) The instantaneous angular velocity of rocker arm CBD; (b) The instantaneous angular acceleration of the rocker arm; (c) The acceleration of point B. Orientation: 1. There is no rigid connection between OA and CBD; 2. The velocity of OA is perpendicular to OA; 3. The velocity va of point A' of CBD, confused with A of OA, is perpendicular to CA and has the same component of v, perpendicular to AB; 4. The acceleration of B is $\vec{y}_B = \vec{Y}_{BA} + \vec{Y}_A$; 5. The acceleration of A' of CBD relative to A of AO is $\vec{Y}_A = \vec{Y}_{A'A} + \vec{Y}_A$. 50 90° THE 45° 131 50 150 Answers: a) $\omega_C = 4.1$ rad/s; b) a = 161 rad/s²; c) y = 8.1 m/s²

3. A linearly polarized EM wave is traveling in the +x - direction. It has a wavelength of 1.66 cm. The electric field vector, which vibrates in the xy - plane, has a maximum value of $E_{max}$ = 174 V/m, and the magnetic field component of the wave can be written a $B = B_{max} \sin (kx-wt)$. a) Find $B_{max}$ (in nT). b) Find $\omega$ (in $s^{-1}$) c) Determine in which plane the magnetic field vector vibrates. d) Calculate the average value of the Intensity (in $W/m^2$) for this wave. e) If this wave were directed at normal incidence onto a perfectly reflecting sheet, what radiation pressure (in $nPa$) would it exert? f) What acceleration (in $nm/s^2$) would be imparted to a 460 g sheet (perfectly reflecting and at normal incidence) with dimensions of 1.00 m x 0.750 m? (Express your answer in vector form.)
