Zorluk: KolayAuthor's Primary Purpose

When installing wheels on a vehicle, mechanics use a calibrated torque wrench rather than an impact gun for the final tightening of lug nuts. Over-tightening lug nuts can stretch and weaken the wheel studs or warp the brake rotors, creating serious safety hazards. Conversely, under-tightening can cause the lug nuts to vibrate loose during operation, potentially leading to wheel separation. By applying the manufacturer's exact torque specifications in a crisscross pattern, the technician ensures that clamping force is distributed evenly across the wheel hub without damaging critical components.

What is the author's primary purpose in this passage?

  1. A
    to describe the physical dangers of warped brake rotors
  2. to explain the importance of using proper torque when tightening vehicle lug nutsCevap
  3. C
    to persuade technicians to stop using impact guns for all automotive repairs
  4. D
    to outline the mechanical steps required to calibrate a torque wrench

Cevap

to explain the importance of using proper torque when tightening vehicle lug nuts
The passage examines both the risks of over-tightening and under-tightening wheel fasteners and explains how applying precise manufacturer torque specifications ensures safety and component integrity. Therefore, the author's primary purpose is to explain the importance of proper torque application.

Adım Adım Çözüm

1
Analyze the topic and supporting details
The text discusses what happens when lug nuts are over-tightened (stud stretching, rotor warping) versus under-tightened (nuts vibrating loose), and how applying exact specifications avoids these issues.
Identifying the consistent theme across all sentences reveals the central topic.
2
Determine the communicative function of the author
The passage provides factual explanations regarding the risks of improper tightening and the necessity of correct torque application.
Understanding why the details were presented clarifies the author's primary goal.
3
Select the statement that best synthesizes the primary objective
The primary purpose is to explain why correct torque application is vital when securing vehicle wheels.
The correct answer must encompass the whole passage rather than a single supporting detail.
