Figure 3 Uniform disk Uniform rod 3) Figure 3 illustrates a physical pendulum comprising a uniform disk having mass M and radius R and a rod having the length R and mass M. The disk is pivotally mounted with a friction-less horizontal axis of rotation that extends through the center of mass of the disk. The rod is fixedly attached to the edge of the disk and it extends vertically downward when the pendulum is in a state of static...

A uniform rod with a mass of m = 1.85 kg and a length
of l = 2.32 m is attached to a horizontal surface with a
hinge. The rod can rotate around the hinge without friction. (See
figure.)
The rod is held at rest at an angle of ? = 65.8° with respect to
the horizontal surface.

Suppose you’re building a contraption which contains a solid rod of length L = 13.1 m and mass 3.8 kg. This rod has its lower end barely above the ground at an angle of 24 degrees with respect to the horizontal, and is ultimately held up by a rope connected at a distance L/4 from the top of the rod making an angle of 28.3 degrees with respect to the rod. The top of the rod may rotate as it...

A block with mass m1 = 8.8 kg is on an incline with an angle θ = 32° with respect to the horizontal. The spring is replaced with a massless rope that pulls horizontally to prevent the block from moving. What is the minimum tension in the rope? Now a new block is attached to the string above the first block on the ramp. The new block is made of a different material and has a coefficient of static friction...

A metal rod of length 76 cm and mass 1.79 kg has a uniform cross-sectional area of 7.7 cm2. Due to a nonuniform density, the center of mass of the rod is 22.2 cm from the right end of the rod. The rod is suspended in a horizontal position in water by ropes attached to both ends (the figure). (a) What is the tension in the rope closer to the center of mass? (b) What is the tension in the...

A block with mass m1 = 8.5 kg is on an incline with an angle θ = 25° with respect to the horizontal. For the first question there is no friction between the incline and the block. 1)When there is no friction, what is the magnitude of the acceleration of the block? 2)Now with friction, the acceleration is measured to be only a = 2.74 m/s2. What is the coefficient of kinetic friction between the incline and the block? 3)...
