Produced a solid mechanics report comparing measured and theoretical belt tensions in a slipping pulley system. The experiment tested belt contact angles of 90°, 180°, 270°, and 360°, measured tight-side and slack-side tensions, and used MATLAB to analyse the belt tension ratio. A logarithmic fit gave a coefficient of friction of about 0.25, and the results showed the expected exponential increase in tension ratio with contact angle. The report also evaluated motor performance, showing efficiency rose to around 70% at moderate torque before decreasing at higher loads due to internal losses. This strengthened my understanding of belt friction theory, torque transmission, experimental data analysis, and the practical limits of real mechanical drive systems.
