- Code to create plot
import matplotlib.pyplot as plt
- Create plot object
fig, ax = plt.subplots()
- Define plot layout
ax.set_xlabel('Lead angle (\u00B0)') ax.set_ylabel('Efficiency (%)')
- Define plot
friction_list = [0.01, 0.02, 0.05, 0.1, 0.15, 0.2, 0.25] for u in friction_list:
x = np.arange(0.5, 75, 0.5) rad_x = np.radians(x) y = ((1 - u*np.tan(rad_x))/(1 + u*(1/np.tan(rad_x))))*100
ax.plot(x,y)
ax.legend(friction_list, title='COF')
