for my sums i made a new axis in my fbd that coincides with both N and F(friction) where the normal is equal to the force of fravity (mgsintheta) i don't understand how i have done my sums wrong
as for the 2nd part i would need 1/1,772 m
the force i calculated was 17.72N
i got this answer by using the following
m=1.3kg
g=9.8m/s^2
theta = 45
coefficient of static friction (us)= 0.9
N=mgsin45
F = (us)N +mgcos45
= (0.9)(1.3)(9,8)(sin45) +(1.3)(9.8)(cos45)
F=17.71
since the motor can lift 0.01N at a 1m radius...
how do go i go about doing step 2 using all of my motor values
we never covered any motor equations in class so I am really new at the motor equations and knowing how to apply them
I have to build a monorail that can climb a 45 degree slope length of the track is 8m. The mass of the monorail is .3kg and it has to carry a mass of 1kg up the slope.im given a 15V electric dc motor with:
Power = 6W at motor stall
no load rpm at 0.07 Amp = 3800
stall torque at 0.4 amp = 0.01N...
