    Angle Block Mass
AI Thread Summary
To determine the optimal angle for pulling a block of mass M with minimal tension, it is essential to analyze the forces involved, particularly the effects of friction. The coefficient of friction influences the angle, suggesting that different coefficients may yield different optimal angles for tension reduction. A force diagram is recommended to visualize the forces acting on the block, including tension, normal force, and frictional force components. By breaking down these forces into horizontal and vertical components, one can better understand how to minimize tension. This approach is crucial for solving the problem effectively.

Homework Statement


What is the best angle to make pulling a block of mass M, possible with the least tension.
Friction is applied, the coefficient varies, does the coefficient change the angle? for which is which angle best...






The Attempt at a Solution


I solved Tension for two different equations T=(mg-Fn)/sin(0) and
T= (Fn*coefficient of friction)/cos(0)
but I haven't really gotten anywhere with it.

Can you draw a force diagram, and then list all forces or force components in the horizontal and vertical directions? That is a good way to start a problem like this.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
