Coefficient of friction problem

AI Thread Summary
The problem involves determining the coefficient of friction for a block of wood sliding down an inclined plane at an angle of 17.157 degrees. The relevant equation for calculating the coefficient of friction is based on the tangent of the angle of elevation. The initial calculation suggests an answer of 2.074, but there is uncertainty regarding the method used to arrive at this figure. Forum participants emphasize providing hints rather than complete solutions to help the original poster understand the problem better. Clarification on the calculation process is requested to ensure accuracy.

Homework Statement



A block of wood is sitting on an inclined plane. One end of the plane is rised until the wood block slides down. The wood block slides down when the plane has an angle of 17.157
degrees . What is the coefficient of friction?


Homework Equations



F/R

The Attempt at a Solution


opposite/ adjacent = tan theta how i worked out my angle

answer should be 2.074 at the end

Angle of elevation, at which the block slid down the ramp, in degree’s (˚)is an average
= tan-1 (opp. /adj.)
= angle θ

Please show how you arrived at the answer...something is not right.
 
Hey ainhaini,
Since you are new to PF I should tell you that you are not supposed to give the whole answer. Just give hints or solve the doubt

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
