The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
