AI Thread Summary
In a Formula 1 scenario, a physicist must calculate the new maximal safe speed for a driver navigating a sharp turn under wet conditions. The driver previously struggled to maintain control at 90 km/h on a dry track, where the tyre-to-road friction coefficient is 0.8. With rain affecting track conditions, the friction coefficient drops to 0.5, necessitating a recalculation of safe speed. The turn's angle is 7º, which influences the dynamics of the vehicle. The discussion emphasizes the need to apply physics principles, particularly the forces acting on a vehicle in circular motion, to derive the new speed.

Homework Statement


You are hired as a physicist in a team of Formula 1. Your driver is driving in the
Germany Grand Prix on the Hockenheim track. After the test session taken in sunny day
you and the driver discuss about the sharpest turn on the track. He tells you that when
driving at 90 km/h he could hardly hold the track. During the Grand Prix, just ten laps to
go, it starts to rain. The driver decides to continue on the same tyres. You have to
calculate the new maximal safe speed at this turn. The tyre-to-road static friction
coefficient is 0.8 for dry and 0.5 for wet road conditions. What would be the speed if the
turn were profiled at an angle of 7º?

start by finding the radius of curvature of the turn …

show us what you get :smile:​
 
Maybe start by getting the equation for forces for a body following a circular path.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
