A digital force transducer outputs a voltage as a function of input force with the following specifications. What is the design-stage uncertainty in the voltage output from the force transducer if the nominal force to be measured is 140N? Select the closest answer. Transducer range: 0-200 N Transducer sensitivity: 0.1 V/N Transducer input power: 10 VDC ± 1 % Transducer output: 0-10 V Transducer linearity error: within 5 mV/N over range Transducer sensitivity error: within 3 mV/N over range Transducer resolution: 0.01 N

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.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
