Harsha made a wind chime using a frame and metal rods. She punched 8 holesin the frame, each 2 cm apart, and then hung 6 metal rods from the frame, asshown in the figure below. The ends of the metal rods are aligned over a line,shown by the dotted line in the figure.1(Note: The figure is not to scale.)If all of the rods are straight and not swaying, then what is the length of RodP?(a) 697 cm(b) 535 cm(c) 765 cm(d) 1117 cm

A light rod of length 200 cm is suspended from the ceiling horizontally by means of two vertical wires of equal length tied to its ends. One of the wires is made of steel and is of cross-sectional area 0.1 cm2 and the other of brass ofcross-sectional area 0.2 cm2. Along the rod the distance at which  weight be hung to produce equal strains in both the wires is n m, where n is. Ybrass=10 x 1011 dyne/cm2 Ysteel=20 x 1011 dyne/cm2.

rigid and uniform one meter long rod AB held in horizontal position by two strings tied to its ends and attached to the ceiling. The rod is of mass 'm' and has another weight of mass 2 m hung at a distance of 75 cm from A. The tension in the string at A is :

A 3.05-kg object is attached to a vertical rod by two strings as shown in the figure below. The object rotates in a horizontal circle at constant speed 6.90 m/s.An object of mass m attached to a vertical rod by two strings each of length 2.00 m is shown. One of the strings is attached to the top of the rod and the other string is attached to the bottom. The distance between where the strings are attached is labeled 3.00 m. The object is rotating away from the rod along a horizontal circular path around the center of the rod.(a) Find the tension in the upper string. N(b) Find the tension in the lower string. Your response differs from the correct answer by more than 10%. Double check your calculations. N

A rod is pivoted around its left end and is supported by a rope that is attached some distance above the pivot point. A mass is placed 61.2 cm to the right of the pivot pointFind the tension in the rope when the mass is in the position shown in the picture to the left

A uniform rod of length L and weight W is placed on a fulcrum a distance of 0.4L from the left end. On the left end is placed a mass of weight 2W and on the right end a vertical force F is applied to keep the system in balance. What are the magnitude and direction of the force F?Select one:a.b.c.d.
