Two blocks on a smooth ramp at 30°, its angle marked θ: m_1 lower down and m_2 above it, tied together by a string parallel to the slope. An applied force F_A pulls m_2 up the slope, and tension T is drawn at both ends of the string, pulling each block toward the other. Each block has its own weight, F_g1 and F_g2, straight down, and its own normal force, F_N1 and F_N2, out of the slope.
