1 to 5 please

1. The motion on a work piece is changing from 0 to 1 meter. AY Oon on a work piece is changing from 0 to 1 meter. A variable linear resistance can be used to measure the signal. The value of this resistance changes from 0 to 2000 S2. A 20 source is available. Develop signal conditioning to provide 0 to 10 V output. 2. To measure the small changes in a work niece, a capacitive-displacement sensor is used Figure-shows the two metal cylinders that are separated by insulation material with thickness of 2 mm and the dielectric constant of 5 given at 1 kHz. The outer radius 155 cm. a) Find the sensitivity in pF/m as the upper cylinder slides in and out of the lower cylinder. b) What is the range of capacity if the height (h) varies from 2.0 to 4.0 cm? 3. An accelerometer has a seismic mass of 100 grams and a spring constant of 2x10 N/m. Maximum mass displacement is +0.01 m. Calculate: a) The maximum measurable acceleration in g b) The natural frequency of oscillation 4. A stain gage has GF = 2.06 and R = 120 Q and is made from wire with Co = 0.0034/C at 25°C The dissipation factor is given as PD-25 mW/ "C. What is the maximum current that can be placed through the SG to keep self-heating error below 1 uof strain? A pump with 2 in diameter pipe, pumps liquid with flow velocity of 3 foot/s. Find the volume flow rate and weight flow rate (lb/min). The weight density is 70 lb/ft?. Figure-1 (Problem 2) Displacement CEK €0,80 = 8.85 pF/m C = 2 1 K € TM

Answer 1

5. Area of pipe = dy - 3.14x (2) - 3.14162 rohome flow rate - Av. - 3.14 x (3x)2) = 113.04 incheſ see. [ foot = 12 met] In toat3 /sec. ů = 113.04 protse = 0.00541 prot/sec. so wt. flow rate – 70 lbs x 0.06541 83/see F73 4. 58 lsfree T1293 Foot/sce.
