To make a graph for the mechanical advantage of a lever, you need to choose values for the length of the effort arm, calculate the corresponding values for the resistance arm, calculate the mechanical advantage, and plot the values on a graph.
To make a graph for the mechanical advantage (MA) of a lever, you need to understand how to calculate the mechanical advantage using the equation MA = L / H. Here's how you can plot it on a graph:
Choose different values for the length of the effort arm (Le) and record them.
Calculate the corresponding values for the length of the resistance arm (Lr) using the equation Lr = L - Le, where L is the total length of the lever.
Calculate the mechanical advantage using the equation MA = Le / Lr.
Plot the values for Le on the x-axis and the corresponding values for MA on the y-axis.
Connect the plotted points to create a straight line graph.
This graph will help you visualize the relationship between the length of the effort arm and the mechanical advantage of the lever.
