AI Thread Summary
Safety and aerodynamic efficiency often conflict in automotive design, as features that enhance safety can compromise a vehicle's sleekness and airflow. For example, additional structural reinforcements and safety features like crumple zones can increase weight and disrupt airflow, reducing aerodynamic performance. Conversely, designs optimized for aerodynamics may lack the necessary safety elements, making them less effective in protecting occupants. Key factors affecting aerodynamic efficiency include vehicle shape, surface smoothness, and the presence of spoilers or other aerodynamic aids. Ultimately, balancing these two goals requires careful consideration of design elements that can enhance both safety and efficiency.

hey guys..totally confused on this question!

How is the goal of safety at odds with aerodynamic efficiency?

OK...the way I am interperting is as. How does the goal of safety interefere with the factor, or progress, of Aerodynamic Efficiency...any help on the answer and where to get started?
 
Physics news on Phys.org
what makes something more aerodynamic?
sleek.
what safety things affect how sleek a car is?
 
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'
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...
