Cho xe tải Hyndai có công suất cực đại 125 KW ở vòng quay 2700 vòng/phút, mô men xoắn cực đại 400Nm ở vòng quay 2400 vòng/phút.
Xe chạy có tổng khối lượng 3500 kg, khối lượng trên cầu sau chủ động là 2400 kg.
Tính các thông số khi tốc độ cực đại yêu cầu của xe là 170 km/h, hộp số có số truyền tăng. Cho hiệu suất truyền lực bằng 0,93; bán kính làm việc của bánh xe 0,5 m; gia tốc trọng trường bằng 10 m/s2.
Tính:
1. Tỉ số truyền lực chính
2. Tỉ số truyền của số 1 theo 3 điều kiện
3. Số cấp số của hộp số
4. Tỉ số truyền các tay số trung gian

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
