- A horizontal force P acts on the top of the 30 N block having a width of 25 cm and a height of 50 cm. If the coefficient of friction between the block and the plane is 0.33. a. What is the value of P for motion to impend? b. Is the motion will impend due to overturning? Show your solution.The rope is once wrapped in stationary dram, as shown with weights. The rope is just on the point of slipping. What is the coefficient of friction?A block of concrete weighs 20 kg, it takes 40 N to start the block sliding on a concrete floor and 10 N to maintain sliding. Calculate the Static coefficiant of friction and calculate the kinetci coefficiant of friction My question is; what is the coefficiant of static and kinetic friction. Ive read throught the book and cant seem to find anything that explains it. I found a formula which reads F = Static coefficiant multiplied by the weight of the block. But that doesnt tell me exactly what the coeffciant of each is, Is it a constant? or does it vary based on the item being moved? Thank you.
- If a piece of block weighing 150 kg is to be pulled up by a winch using two cables on a 25 deg inclined plane, find the least force each cable will be subjected to set the block in motion. Assume the coefficient of friction to be 0.25.(A) If the power losses in Pelton wheel due to bucket friction is given by 1 POK V -u)? where K is a dimensionless constant. Derive an expression to the ratio that gives maximum power. V,In an experiment to find the coefficient of static friction, two plates (e) made of the sam material, m, = 200 gm, and m,= 400 gm. Each plate is put on the top of the same inclined plane, and we start to increase the inclination angle (z Jeo Legb). e Select one: a. The coefficient of static friction determined using m, is lower b. The coefficient of static friction determined using m, is lower will slide at lower angle than m, c. m1 d. Both will slide at the same angle
