A rope wraps an angle θ around a pole. You grab one end and pull with a
tension T . The other end is attached to a large object, say, a boat. If
the coefficient of static friction between the rope and the pole is μ,
what is the largest force the rope can exert on the boat, if the rope is
not to slip around the pole?
它是說有個繩子以θ角纏在竿上?????(這是怎麼纏的阿)
你用T的力抓住繩子的一端
繩的另一端纏在一艘船上
如果繩子和竿間的靜摩擦係數是μ
繩子能拉船的最大力為?
設繩子在竿上沒有滑動
題目是這樣對吧
可是他第一句我就不太懂了
請知道的大大能告訴我
謝謝^^
