A rod, 1 cm2 x 200 cm and mass 2 kg, is clamped at its center. When vibrating longitudinally it emits its third overtone in unison with a tuning fork making 6000 vps. How much will the rod be elongated if, when clamped at one end, a stretching force of 980 N is applied to the other end?

Two uniform rods of identical mass and identical length are rotating with identical rotational kinetic energy. The first rod is rotating about and axis that passes through its left end and points perpendicular to the rod. The second rod is rotating about an axis that passes through its center and points perpendicular to the rod. Which rod has a larger magnitude of angular velocity? a. They both have the same magnitude of angular velocity. b. The second rod. c. The...
A uniform rod of length 67.5 cm and mass 0.234 kg is placed on a fulcrum at a distance of 47.7 cm from the left end of the rod. At what distance (in cm) from the left end of the rod should a 0.805 kg mass be hung to balance the rod?
a sign of mass 20.0 kg is supported at the end of a uniform beam of mass 10.0 kg and length 2.00!m. the beam makes an angle of 30.0 degrees with the horizontal. a wire is attached from the end of the rod to a point on the wall and makes an angle if 20.0 degrees to the horizontal. what is the tension of the wire. what are the magnitudes of the horizontal and vertical components of the reaction force...
A rigid, uniform, horizontal bar of mass m1 and length L is
supported by two identical massless strings. (Figure 1) Both
strings are vertical. String A is attached at a distance d<L/2
from the left end of the bar and is connected to the ceiling;
string B is attached to the left end of the bar and is connected to
the floor. A small block of mass m2 is supported against gravity by
the bar at a distance x from...
6. A uniform rod of length 5.0 m and weight 60.0 N is supported at its right end by a vertical cable and at a point 1.5 m from the left end by another vertical cable, as shown. Find the tension in both cables. Sm 3.5 m
A horizontal length of current carrying wire is suspended from two identical flexible leads that are under tension due to the weight of the wire. The wire is oriented at right angles to a uniform magnetic field that has a magnitude of 2.5T and is directed into the screen of the figure. The length of the wire is 5 cm and its mass mis 10g. What current will produce a magnetic force on the wire that is just sufficient to...
