Physics help with torque! The crank arm of a bicycle is 16.5 cm long. If a 52.0 kg woman puts all weight on one pedal, how much torque is developed a. when the crank is horizontal b. when the crank is vertical
can u help me with a.
But anyway A is...84.2Nm
give me one second... F=mg t(torch)=rF sin emtyset sign emptyset sign =90 degrees t(torch)= (0.165)(52.0)(9.81)(SIN165) t(torch)= 84.2Nm
there you go...sorry I couldn't help you with b...
i have another question though .. if a force of 4 N is needed to open a 1m wide door when applied at the edge opposite the hinges what force must be applied to open the door if you push against the door 10 cm from the hinged side
I'm not sure...sorry...
