A block of mass is held against a rough vertical wall by pressing it with a finger. If the coefficient of friction between the block and the wall is and the acceleration due to gravity is calculate the minimum force required to be applied by the finger to hold the block against the wall ?, 12/31/2019 · A cubical block of side ‘a’ is held at rest, against a rough vertical wall by applying a force `F` acting along the centre. The mass of the block is `m`. Taking acceleration due to gravity as ‘g’ , determine `(i)` The minimum coefficient of friction between the block and wall `(ii)` The torque by normal reaction about the centre of mass, A block of mass 1 kg is held at rest against a rough vertical surface by pushing by a force F horizontally. The coefficient of friction is 0.5. When, Kinetic energy after crossing the rough patch = 1/2 x 1.2 x 2.3² = 3.174 J . Loss of energy = 365 d² – 3.174 This loss is due to negative work done by frictional force . work done by friction = friction force x width of patch = ?mg d , ? = coefficient of friction , m is mass of block , d is width of patch = .44 x 1.2 x 9.8 x .05 = .2587 J, Part B (Mechanical Energy and Conservation of Energy) Problem B1: A block of mass m = 0.2kg is held against but not attached to a spring of so compressed by 20cm, as show below. When released, the block slides som the rough incline before coming to rest . but not attached to a spring of stiffness constant ka 50cm 20cm * = 0, Usp = 0 Low Ug = 0 …
