An accelerometer is used to measure the amplitude of a simple sinusoidal oscillation with period of 0.031 seconds. if the output voltage from the accelerometer is 0.45 vpp , and the accelerometer calibration is 0.14 v/g, what is the displacement sensed by the accelerometer in mm?

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Asteel wire of 2 mm diameter is fixed between two points located 2 m apart. the tensile force in the wire is 250n, if its density of steel is given by 7830 kg/m3 the fundamental frequency of vibration hz? ?

Ahelical coil spring has a mean diameter of 50 mm, a wire diameter of 5.5 mm and is wound with a pitch of 10 mm. the spring steel has an ultimate strength of 1250 mpa. find the force needed to compress the spring solid and the wire stress in this condition. state whether the spring will return to its initial length.
