Review

The greater the angle \(\theta_{\mathrm{slip}}\) beyond which the box begins to slide, the greater the value of tan \(\theta_{\mathrm{slip}}\) and hence the greater the coefficient of static friction must be to provide the necessary friction force. Note that Equation 5-5 does \(\textit{not}\) involve the weight of the block. A plastic block on a wooden ramp will begin to slide at the same angle \(\theta\) regardless of its weight.
