+    A slider crank mechanism is a common mechanical system that converts rotational motion into linear motion.
+    It consists of a crank, a connecting rod, and a slider.
+    The crank rotates about a fixed axis, the connecting rod connects the crank to the slider, and the slider moves linearly along a guide or track.
+  </p>
+  <p>
+    Here are some things to keep in mind when solving problems involving slider-crank mechanisms:
+  </p>
+  <ul>
+        <li>The velocity of the slider is purely tangential to the path of the slider.</li>
+        <li>The acceleration of the slider is purely tangential to the path of the slider.</li>
+				<li>The slider has a reaction force normal to the path of the slider.</li>
+    </ul>
