The transmission angle is always numerically equal to the angle between the coupler and rocker.
举一反三
- Measured<br/>in main section, the angle between the rake surface and the reference<br/>plane is (). A: rake γo B: clearance angle αo C: Cutting edge angle κr D: Inclination angle λs
- The rotation angle of the cross section at the maximum deflection of the beam must be equal to zero. ( )
- The cantilever beam shown here is subjected to two equal and opposite couples，for the section B（ ）.[img=414x136]1803a25c3173b7f.jpg[/img] A: The deflection is zero, the angle of rotation is not zero B: The deflection is not zero, the angle of rotation is zero C: Deflection and angle of rotation are both not zero D: Both deflection and angle of rotation are both zero
- The rotation angle of the cross section at the maximum deflection of the beam must be equal to zero. ( ) A: 正确 B: 错误
- The tool tip of the external turning tool is installed higher than the workpiece rotation axis, the working rake Angle of turning tool is （ ）than that of marked rake angle A: lager B: smaller C: equal to D: unidentified
