Two voltmeters are connected in series. Voltmeter A is rated at 100 volts full-scale deflection and has a sensitivity of 1,000 ohms per volt. Voltmeter B has a 1-ma movement and a full-scale rating of 150 volts. Voltmeter B reads 57 volts, but the pointer on voltmeter A is badly bent so its reading cannot be trusted. What is the total voltage across the two voltmeters?​

On a average work day more than work place firs are reorted

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
