A block of mass M = 539.0 g sits on a horizontal tabletop. The coefficients of static and kinetic friction are 0.549 and 0.391, respectively, at the contact surface between table and block. The block is pushed on with a 13.6 N external force at an angle \theta with the horizontal. a) What angle with respect to the horizontal will lead to the maximum acceleration in horizontal direction of the block for a given pushing force? (Give your answer in degrees and use the unit "deg") b) What is the value of this maximum horizontal acceleration?
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.
A block rest on a horizontal board. the board is gradually tilted upward and the block just begin to slide when the angle of inclination is 21°, a. Find the coefficient of static friction between the block and the board. b. After the block starts moving it is found that it will keep sliding at constant speed when the angle tilt to 15°. Find the coefficient of kinetic friction. Express in terms of variables the W and other forces.

01/ A porter governor its central load is 18 kg and the weight of each ball is 2 kg. The top arms are 25 cm while the bottom arms are each 30 cm long and all arms pivoted on the axis of Governors (Homework's) tation. The friction of the sleeve is 14 N. If the top arms make 45° with the axis of rotation in equilibrium position, find the speed of the governor at that position. 021 The four arms of a proell governor are 300 mm long and are pivoted on the axis of rotation. Fach ball weight 5 kg and is carried on an extension 100 mm long of the lower arms. The central load on the sleeve is 80 kg. Calculate the equilibrium speed of the governor to radius of rotation of 150 mm when the extension arm is vertical. Q3/ A porter governor has equal links, each 250 mm long pivoted at the axis of rotation, each ball is of mass 4 kg and the mass of the central load is 15 kg.

Sign In Example #4 : The coefficient of friction between the 20KN block A and the 40KN block B of Figure below is 0.40. The coefficient of friction berween block B and the horizontal plane is 0.15. Determine the force P required to cause motion of block A to impend to the right. SOLUTION : There are 2 case for this problem : Case 1 about the force P will cause motion of A to impend to the right alone without moving Block B Case 2 about the force P will cause motion of A to impend to the right with moving Block B with it in same time. تم انضمام علي عصام کاظم حميد إلى الاجتماع. ۳۷ مشارك آخر Salam عبد الوهاب أنت
