In mechanical design, the term ________ refers to thestudy of the forces and moments acting on a body.答案：Statics6. The unit of pressure in the International System of Units (SI) is ________.答案：Pascal (Pa)三、简答题7. Explain the difference between static and dynamic friction.答案：Static friction is the force that must be overcometo start moving an object at rest, while dynamic friction is the force that opposes the motion of an object that isalready moving.8. Describe the purpose of a gear in a mechanical system.答案：A gear is used to transmit motion and force from one part of a system to another, often changing the speed and/or direction of the motion.四、计算题9. A hydraulic press has a piston with an area of 0.02 m². If the pressure applied to the piston is 5 MPa, calculate the force exerted by the piston.答案：Force = P ressure × Area = 5 × 10⁶ Pa × 0.02 m²= 100,000 N10. A lever is balanced when the product of the effort force and its distance from the fulcrum is equal to the product of the load force and its distance from the fulcrum. If the effort force is 300 N and the load force is 1200 N, and the effort is applied 2 m from the fulcrum, calculate the distance from the fulcrum to the load.答案：Let the distance from the fulcrum to the load be\( x \). According to the principle of levers, \( 300 N\times 2 m = 1200 N \times x \). Solving for \( x \) gives\( x = \frac{300 N \times 2 m}{1200 N} = 0.5 m \).五、论述题11. Discuss the importance of mechanical vibrations in the context of machinery operation and maintenance.答案：Mechanical vibrations are crucial in machinery for several reasons. They can indicate the health of a machine, with abnormal vibrations often signaling a problem such as imbalance, misalignment, or wear. Monitoring vibrations can help in predictive maintenance, preventing breakdowns and extending the life of machinery.12. Explain the concept of stress concentration in mechanical components and its implications.答案：Stress concentration occurs in mechanical components where the stress is higher than the average stress due to geometrical discontinuities or material defects. This can lead to premature failure of the component under load, as the high-stress areas are more susceptible to fatigue and cracking. Designing to minimize stress concentrations and using materials with good fatigue resistance can mitigate these effects.。
