Maria has severe arthritis and can apply a maximum force of only 25.5 N when opening her front door.
(a) How much more torque would Maria be able to apply if she purchased a lever-style door opener with a handle 12.7 cm long compared to her conventional doorknob with a radius of 3.74 cm?
(b) How much less force would she need to apply to the new door handle in order to maintain the original amount of torque she had with her old doorknob?
