I would appreciate greatly your assistance on the following problem:
The answer given in the book is:
Acceleration of wedge: $0.7 \frac{m}{s^2}$.
Reaction between wedge and horizontal plane: $173.25 N$.
I would like to understand how these values are derived. So far I have attempted to resolve the forces in the system as follows:
Eqn 1) $R_{5} - R_{3} = 10\sqrt{2}a$ [wedge (i)]
Eqn 2) $R_{5} - T = 5b - 5\sqrt{2}a$ [M5 (i)]
Eqn 3) $5\sqrt{2}g - R_{5} - T = 5b$ [M5 (j)]
Eqn 4) $T - R_{3} = 3b-3\sqrt{2}a$ [M3 (i)]
Eqn 5) $T + R_{3} - 3\sqrt{2}g = 3b$ [M3 (j)]
Any help at all would be very much welcome.
