A bead is allowed to slide along a wire, which is shaped in the form of a parabola, described by the function, y(x) = (1/ α)* x2 , where y is the height above the ground and α is a positive constant. The coefficient of static friction between the wire and the bead is μS . Work out the maximum height above the ground at which the bead can still be placed without sliding down. Your answer should depend only...

2. The ends of uniform rod AB can slide along the horizontal floor and the inclined plane. At the instant shown, the end A is moving at a constant velocity of 2.5 to the left. Using the concept of the instantaneous center of zero velocity, determine (a) the angular velocity of the rod and (b) the velocity of end B of the rod. Also determine the acceleration of the mass center of the rod, G, which is located at the...

A flat straight grass slide makes an angle of 28° with the horizontal and is 12 m long. A mat starts sliding from rest at the top of the slide. The mat has constant acceleration and it reaches a speed of 2.5s at the bottom of the slide. Let the mass of the mat be m (in kg) and the coefficient of sliding friction between the mat and the slide be μ 12 m mat 283 Model the mat as...

The figure on the right illustrates a ball which is a uniform solid sphere having mass M and radius R. The ball is initially traveling in the positive direction with pure translational motion along a friction-less region of a horizontal surface (i.e. it slips with angular speed ω0-0). The initial translational speed of the ball is Vo. The friction-less region extends to a region having coefficient of kinetic friction Figure for WAH #10 V. Friction Friction-less No longer slipping '...

A wooden block of mass M sits on a flat metal table which can be made to oscillate horizontally in simple harmonic motion. The coefficient of static friction between the block and table is mu. When the table oscillates, the horizontal position x of the block can be expressed as x(t) = L cos(omega t) where L is the amplitude of the oscillation and omega is the angular frequency of the oscillation. For a given amplitude, what is the maximum...
