Answer: 567 N
Explanation:
If the weight of the person and the bike are supported equally by the two tires, this means that the force acting on each tire, is half of the total weight.
We know that the gauge pressure in one tire, by definition, is equal to the force on the tire, over the contact surface between each tire and the road, so we can write:
P= F/A = (mrider g + mbike g) / A = (Fgrider + 7.5 kg. 9.8 m/s2) / 703 mm2 (1)
As the pressure data is given in lb/in2, it is needed to convert to N/mm2, as follows:
65.5 lb/in2 = 0.455 N/mm2.
Replacing in (1), and solving for Fgrider, we have:
Fgrider = 567 N
Answer:
friction coefficient on the rough road is 0.117
Explanation:
As we know that car is taking turn on flat rough road
So here we can say that required centripetal force for circular motion of car is due to frictional force
So we have
now we have
so we have
