The two uniform bars are identical. The mass and length of each bar are m= 30 kg and L=1.6 m. The top bar rotates around point A, coordinate , locates the bar, and force F(t) = 500 sin 60t (in N) is being applied to the end of the bar. A spring with k = 10000 N/m connects the top bar to a fixed point. The bottom bar rotates around its center at point B and coordinate 0g locates this...

The mass of uniform bar ABC is MBAR = 30 kg and its overall length is L=1.6 m. The bar rotates around point 0 and force F(t) is being to the end of the bar at C. The masses of pistons A and B are ma = 5 kg and mg = 8 kg , respectively. k= 20000 N/m for each spring and c=500 N-s/m for the damper connected to piston A. Coordinate e locates the bar, coordinate x, locates...

ceiling G 12 Bar AB of mass m and length L is attached to two springs at its ends and is held down with cord C as shown in the diagram. When the bar is horizontal, spring A exerts a force Fo and spring B exerts a larger force F (Cord C is needed to hold the bar in place because both forces F, and F, are greater than the weight of the bar). 1-At what distance x from point...

The figure shows the mass m at the end of a bar of length / is restrained by a spring and dashpot. The mass is initially at rest and vibrates in the vertical plane under the action of the force F(1). Determine the equation of motion, natural frequency, and damping ratio of the system when m = 45 kg, k = 9700 N/m, c = 950 N.s/m, a - 0.8 m, and I = 2 m. Neglect the mass of...

A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform
density is placed upon a horizontal, frictionless surface. A small
rubber puck (mass 250 g) slides towards the bar with a speed (2
m/s) directed perpendicular to the bar. It collides perfectly
elastically with the bar at a distance (d) from the center of mass
of the bar in such a way that the puck rebounds with a velocity (1
m/s).
a) What is the value...

The figure below shows a bar of mass m = 0.280 kg that can slide without friction on a pair of rails separated by a distance ℓ = 1.20 m and located on an inclined plane that makes an angle θ = 29.5° with respect to the ground. The resistance of the resistor is R = 2.20 Ω, and a uniform magnetic field of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region...

The 4 kg slender bar shown is 2 m in length. The bar started from rest in an initial position relative to an inertial reference frame. For the position shown, v,-21+6) m/s and ???- 12k rad/s. Treating the bar as a rigid body, find the work done on the bar as it moved from its initial position to its present position. 30° 65.9 Nm
