A block of mass M = 0.5 kg is attached to one end of a light string going over a massless, frictionless pulley. The other end of the string is fixed at the floor while the pulley is attached to a spring with k = 50 N/m as indicated in the figure. The block is on a table which is hinged at the wall. At this position the spring is in equilibrium length. Then the table is released suddenly and the system starts to oscillate. What is the maximum speed of the block? Yo W

A uniform beam of length, L, and mass, M, is freely pivoted at one end about an attachment point in a wall. The other end is supported by a horizontal cable also attached to the wall, so that the beam makes an angle phi with the horizontal as shown below. To answer the questions below, find algebraic expressions for the tension in the cable, the angular acceleration of the beam, should the cable break, and the resulting angular velocity as the beam falls through the vertical position. A. If L = 2.4 m, M = 5 kg, and phi = 45o, then what is the tension in the cable? B. If the cable snaps, what is the angular acceleration about the pivot point? C. What is the angular velocity of the falling beam, just as it hits the wall?
2 Your answer is partially correct. Try again. In the figure, a slab of mass m, = 40 kg rests on a frictionless floor, and a block of mass m, = 9 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force F of magnitude 102 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab? u = 0- (a) Number T-7.4 -7.4 Units m/s^2 (b) Number i+ Units m/s^2 -0.88 Click if you would like to Show Work for this question: Open Show Work SHOW HINT LINK TO TEXT LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE 10:50 PM search ENG 4/4/2021 ond 111Pgup) pri sc DOUSE insert dele home break 13) 23 bac 3 5. 4 R.

A beam is supported by a hinged joint at one end (O) and by a spring at the other end (A) as shown in the figure. The stiffness of the spring is such that the beam end A lies directly under the spring attachment point B when the spring is at its free length (no force). Using Hamilton's principle, develop the Euler-Lagrange equation of motion for the system when subjected to 1. A time-dependent vertical force applied at end A of the beam. 2. A time dependent force at end A of the beam that remains oriented perpendicular to the beam for all angles of the beam. Assume the following for your analysis 1. The beam is rigid. 2. The beam is uniform, i.e. its mass per unit length is constant) 3. The thickness of the beam is small compared to its length 4. The spring stiffness is constant. 5. The spring mass is small and can be ignored. 6. The angular displacements of the beam are not necessarily small. D F(t) F(t)
The thin rod of the figure has a mass of 15kg and is attached to a spring of constant K = 50 N/m at one end, which has an unstretched length of 1.5 m. If the rod is released from rest in horizontal position (ø = 0°) and only conservative forces act on it, determine: a) What is the moment of inertia of the thin rod around the axis of rotation in A? b) What is the angle at which the rod is momentarily resting again? c) What is the maximum angular speed of the route?

The strings AB and AC connect 500-g mass A to the vertical shaft BC. When the shaft rotates with a constant angular velocity of 15 rad/s, the ball has circular motion in the horizontal plane with the strings having angles of ? = 55° shown in the figure. Find the tension forces at the strings AB and AC.
