Question

please answer my questions in the picture.

expecting a detailed explanation, Thankyou.

why it is not vt=vocos

why we dont use an at

2 In the timing mechanism shown in Figure 1, the motion of the pin A in the fixed circular slot is controlled by the guide B, which is elevated by its lead screw with a constant upward velocity t 2 ms. The radius r of the slot is 230 mm. For pin A and for the instant position for which 0-30 (a) Calculate the tangential speed (b) Calculate the normal and the tangential components of acceleration. that it passes the itis not 1P3H solutions/2 (a) Vertical component of velocity.
