Chapter 1, Problem 1P
For the devices described in Problems1−14, write a set of functions and design requirements in a similar manner to those in Section1−4. You or your instructor may add more specific information to the general descriptions given.
- The hood latch for an automobile.
Expert Solution & Answer
To determine
Functions and design requirements for hood latch for an automobile.
Explanation of Solution
Functions for hood latch for an automobile are:
- Hood latch is the type of mechanical component that keeps the hood closed shut.
- The latch keeps the hood connected to the automobile.
- It prevents the accidental opening.
Design requirements for hood latch for an automobile are:
- Spring must have enough stiffness to hold the hood.
- Hood latch must be able to work minimum 8 hr per day.
- Applied force to the hood latch should not be too large.
- Mechanical efficiency must be greater than 95%.
- Cost must be moderate.
- Less wear producing material is selected.
- All government and industry safety standards must be met.
