MECT361 Mechatronics Components and Instrumentation 8.1. Why is it not possible to connect sensors such as thermocouples, strain gages, and accelerometers directly to a digital computer or microprocessor? PLEASE GIVE ME THE REFRENCE I Will get zero if you didn't put the refrence

Answer all parts show work

2. [5 points] (a) Vs (b) R Rx IG contact Ammeter A A potentiometer is to be used to measure the voltage Vm as shown above. L is the length of the potentiometer and x is the length of resistance to the contact point when the measurement is ready to be taken. VmRm What conditions are required for a measurement to be taken? Does this place the system in null or deflection mode for the measurement? How is Vm calculated from the measured length x? Provide a mathematical expression. No written explanation required.

Explain the significance of the following information given in the specification of transducers: (a) A piezoelectric accelerometer. Non-linearity: *0.5% of full range.

Q1) The redesigned brake caliper is manufactured using SLM from Titanium Ti6Al-4V alloy powder. How many SLM machines are required to manufacture parts for 450 vehicles which are to be built in a 20-month production period. The following parameters are in effect:  5 parts can be built at once on a single machine The caliper has a height of 173mm. Each layer is 64 µm thick 4 scanning lasers are used which share the scanning time for each layer The average laser scanning time for each layer with a single laser is 63 seconds The powder recoating time for every odd numbered layer is 18.6secondsand 38.75 seconds for every even numbered layer Every 8th layer is scanned twice, at 2.3 times the usual laser scan speed to provide additional heat input for in-situ heat treatment The SLM machine operates at a duty rate of 42% of the 24-hour day, Monday to Friday, for 48 weeks of the year, with 10% of production time lost to unscheduled downtime.

3) The probe in AFM techniques is 4) Nanoscale materials are so interesting, especially in the industry sector due to 5) and and------ are considered one of the important metal nanoparticles that are used as vigorous catalysts in chemical reactions. 6) The synthesis process of nanoparticles that use the liquid phase as bulk materials is process. 7) The process that uses ultrasound frequency greater than 20 kHz is known as process. is outside the sphere. 8) The process that depends on using atom by atom to fabricate nanoparticles are called 9) Micelles are called reverse micelles if is inside the sphere and 10) The pressure equal to 50 Torr is normally equal to ------Pa.

Describe the role of microchips in the automotive industry, including applications in advanced driver-assistance systems (ADAS) and autonomous vehicles.

S 3: Light gates may be used to measure the speed of projectiles, such as arrows shot from a bow. English longbows made of yew in the 1400s achieved launch speeds of 60 m/s. Determine the relationship between light gates and the accuracy required for sensing the times when the light gate senses the presence of the arrow.

OBJECTIVE TYPE QUESTIONS 1. The velocity ratio of two pulleys connected by an open belt or crossed belt is 2. (a) directly proportional to their diameters (b) inversely proportional to their diameters (c) directly proportional to the square of their diameters (d) inversely proportional to the square of their diameters Two pulleys of diameters d, and d, and at distance x apart are connected by means of an open belt drive. The length of the belt is (a)(d+d₁)+2x+ (d₁+d₂)² 4x (b)(d₁-d₂)+2x+ (d₁-d₂)² 4x (c)(d₁+d₂)+ +2x+ (d₁-d₂)² 4x (d)(d-d₂)+2x+ (d₁ +d₂)² 4x 3. In a cone pulley, if the sum of radii of the pulleys on the driving and driven shafts is constant, then (a) open belt drive is recommended (b) cross belt drive is recommended (c) both open belt drive and cross belt drive are recommended (d) the drive is recommended depending upon the torque transmitted Due to slip of the belt, the velocity ratio of the belt drive 4. (a) decreases 5. (b) increases (c) does not change When two pulleys…
