1. 对于大船, 因为钱江潮对它的影响较小, 所以它只要考虑水流对它的作用,在河中抛锚,或在岸边用缆绳系住岸边的木桩可以防止船被水流冲走, 船头朝上可以减少水流的阻力.

2, 对于小船,除了述原因外,还需考虑浪潮拍打时对小船的损害,距水面差不多2—4米的距离,是为了减少浪对小船的损害

3. 没有图, 只能设连接动滑轮的链条有两条
则 每条分担的重量为3000N/2=1500N
根据杠杆原理, 动力*动力臂=阻力*阻力臂
F * 0.1M=1500N * 0.08M
解得 F=1500N * 0.08M / 0.1M =1200N

解题思路：（1）根据有20辆汽车装运A、B、C三种水果，可以表示出有20-x-y辆车装运C种水果，从而得出答案，
（2）从而根据水果总吨数为42，再根据（1）中运费与车辆数即可表示出w．

（1）由题意得：
2.2x+2.1y+2（20-x-y）=42
化简得：y=20-2x （3分）
∵

x≥2
20−2x≥2，
∴x的取值范围是：2≤x≤9．
（2）由题意得：
W=6×2.2x+8×2.1（-2x+20）+5×2（20-x-y），
=-10.4x+336，
∵k=-10.4＜0，且2≤x≤9
∴当x=2时，W有最大值，
w_最大=-10.4×2+336=315.2（百元）
∴A：2辆；B：16辆；C：2辆．
∴相应的车辆分配方案为：
2辆车装运A种水果，用16辆车装运B种水果，有20-x-y=2辆车装运C种水果．
