A sphere of mass M is suspended from the left-hand end of the rod.
Where should a second sphere of mass 2M be suspended so that the rod remains horizontal? What is the tension in the cable? In equilibrium, what are the magnitudes L and T? An ankle weight 89 N attached a distance of 0. What is the torque due to this weight?
What is the net force on the rod? Choose Wisely! Where do you need to place a 2 kg weight to balance it? Which of the two people is supporting the greatest weight? The person on the left is supporting the greatest weight 2. The person on the right is supporting the greatest weight 3. Equilibrium Example A 75 kg painter stands at the center of a 50 kg 3 meter plank.
The supports are 1 meter in from each edge. Calculate the force on support A. Equilibrium Example How far to the right of support B can the painter stand before the plank tips?
Equilibrium Example A 50 kg diver stands at the end of a 4. Neglecting the weight of the board, what is the force on the pivot 1. Una escalera de 15 kg descansa contra una pared lisa. Un hombre con una masa de 78 Kg.
It takes force to accelerate block 2. It takes force torque to accelerate the pulley. The Hammer! Rotation ACT Two wheels can rotate freely about fixed axles through their centers.
The wheels have the same mass, but one has twice the radius of the other. It is connected to an object of mass m2 by a massless string. The string turns the pulley without slipping or stretching. If the glider and object are released, the glider accelerates to the right and the object accelerates downward.
During this motion, what is the relationship among T1 the tension in the horizontal part of the string , T2 the tension in the vertical part of the string , and the weight m2g of the object? The weight of the string is negligibly small compared to the weight of the hoop. If the free end of the string is held in place and the hoop is released from rest, the string unwinds and the hoop descends.
As the hoop descends, how does the tension in the string magnitude T compare to the weight of the hoop w? Which of the following forces exerts a torque on the bowling ball about its center? Si el bloque se suelta desde el reposo. The string does not slip on the pulley. T Starting at rest, how long does it take for the mass to fall a distance L.
A string is wrapped several times around the rim weight w of a small hoop. As the hoop descends, what is the acceleration of the center of mass of the hoop? Dos masas penden de una polea. La polea tiene una masa de 0,2 Kg. Rolling Una esfera uniforme de 2 Kg. What is its acceleration?
It is an unknown, so we must solve for it. What is the velocity of the bottom of the wheel relative to the ground? What is the velocity of the top of the wheel relative to the ground? Si un objeto rueda sin resbalar, la longitud del arco entre dos puntos de contacto en la circunferencia es igual a la distancia lineal recorrida. Inertia Rods Two batons have equal mass and length. Rolling Race Hoop vs Cylinder A hoop and a cylinder of equal mass roll down a ramp with height h.
Which has greatest KE at bottom? Preflight Rolling Race Hoop vs Cylinder A hoop and a cylinder of equal mass roll down a ramp with height h. Which has greatest speed at the bottom of the ramp? Compare the kinetic energy of the kids on the two rides. Energy Conservation!
Determine the ratio of the translational to rotational KE. One has twice the radius of the other. When an object rolls down an inclined plane, potential energy is converted to translational and rotational kinetic energy. This makes the rolling slower than frictionless sliding. Massless Pulley Example Consider the two masses connected by a pulley as shown. Use conservation of energy to calculate the speed of the blocks after m2 has dropped a distance h.
Assume the pulley is massless. Massive Pulley Act Consider the two masses connected by a pulley as shown. If the pulley is massive, after m2 drops a distance h, the blocks will be moving A faster than B the same speed as C slower than Slower because some energy if it was a massless pulley goes into spinning pulley!

University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity and magnetism, and Volume 3 covers optics and modern physics. This textbook emphasizes connections between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject.
