A120 kg machine is mounted on a spring of stffness 7.68x10 n/m with no viscous damping. during operation the machine develops a harmonic force at a frequency of 100 rad/s. is it better to use an accelerometer of natural frequency 600 rad/s or a seismometer of natural frequency 600 rad/s to measure the vibrations? explain.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
