Two springs with different force constants have one end fixed. Their free ends are pulled together to connect.

In a box with vertical sides, two springs have one end fixed on opposite sides of the box. The free ends are distance S= .64 meters apart. SEE ATTACHMENT #1 for a diagram of initial and final conditions. When the free ends are pulled together and joined, find the change in the length of each spring. Their force constants are: Spring #1, has k1= 54 nt/m, and Spring #2, has k2= 36 nt/m.

A rectangle made of two uniform bars lengths L, mass A, and two of length W, mass B, oscillates with SHM about an axis at one corner.

A rectangular frame is made from two thin, uniform bars of length L= 4 m, mass A= 6 kg, and two of length W= 3 m, mass B= 1.5 kg. The frame is placed on a pivot axis at one corner and executes SHM about that axis. Find the period of this SHM oscillation. SEE ATTACHMENT #1 for a diagram of the given parameters.

Traveling waves represented as a sine curve, with general information and basic equation.

Some parameters which all traveling waves have include its wavelength (lambda), period T, wave speed v, amplitude ym, etc. ATTACHMENT #1 is a diagram of a typical wave, a sine curve, with points A, B, etc. identifying various points and lengths of a wave. PART a. On ATTACHMENT #1, in the spaces shown after the parameters listed, write in the letter(s) which that parameter describes. Then see ATTACHMENT #2 to check your work for correct answers and see explanations in the posted solution. PART b. For a moving sound wave, with frequency is 440 cy/sec, traveling at velocity 346 m/sec, find the wave length of the sound. PART c. For a moving wave on the surface of the sea, if 12 crests move p... click for more
