汽车发生爆胎后,需要用千斤顶帮助拾起汽车方便换胎。当摇动把手时,就能使水平面上的千斤顶的两臂(长度相等)靠拢,顶起汽车。图(a)、(b)为汽车内常备的两种类型的千斤顶,一种是“y”一种是“y”形,另一种是“菱形”,摇动手柄,使螺旋杆转动,A、B间距离发生改变,从而实现重物的升降。若物若物θ,重为G,AB与AC间的夹角为0,螺旋杆保持水平,不计杆自身重力,则图(a)、(b)两千斤顶螺旋杆的拉力大小之比为:D.2:3A.1:1,:2

115.(12分)如图所示,倾斜轨道AB、水平轨道BO、半圆轨道CD、圆弧轨道EF固定在同一竖直平面内,倾斜轨道AB与水平轨道BC通过一小段长度不计的圆弧连接,水平轨道BC与半圆轨道CD相切于C点,圆弧轨道的E点与半圆轨道CD的D点在同一竖直线上,E点略低于D点。一物块(可视为质点)从点水平抛出,恰好在A点以沿倾斜轨道向下的速度滑上AB轨道,然后滑入水平轨道BC(无机械能损失),随后进入半圆轨道0,并且滑上圆弧轨道EF。已知物块不会从A点离开AB轨道,水平轨道BC的长度L=1m,半圆轨道CD的半径=0.5m1,,圆弧轨道EF的半径R=1m,圆弧EF对应的圆心角为60^,,物块与水平轨道BC间的动摩擦因数=0.05,其他轨道均光滑,重力加速度大小g=10m/s^2,空气阻力不计。(1)若物块恰好能到达D点,求物块在D点和B点的速度大小。(2)若物块能到达E点又恰好不越过F点,求物块能通过D点的次数。0^

13.(10分)同种介质中,甲、乙两列简谐波相向传播,计时开始即示,已知甲、乙两列波的波长分别为2λ、λ,经过一段时间t0,,两列波的波谷第一次相遇,求:(1)乙的波速与甲的周期;(2)从计时开始经过多少时间甲、乙两列波第一次相遇.
