Question

A two-bar linkage rotates about the pivot point O, as shown. The length of members AB and OA are 2.0 m and 2.5 m, respectively. The angular velocity and acceleration of member A are:

a) Dependent on the mass of the members.
b) Related to the pivot point O.
c) Equal to zero due to fixed lengths.
d) Constant and linearly increasing.

Answer 1

The angular velocity and acceleration of member A in a two-bar linkage are related to the pivot point O.

Step-by-step explanation:

The angular velocity and acceleration of member A in a two-bar linkage are related to the pivot point O. As the linkage rotates about O, the angular velocity and acceleration of member A change depending on its position relative to the pivot point. The length of the members AB and OA does not directly determine the angular velocity and acceleration. The mass of the members is also not directly related to the angular velocity and acceleration.
