According to my understanding you are working on motion study. If so, then you have a multiple options available for you:
(1)- Create a mate relationship with equation, Solidworks support this feature. But make sure not use any mechanical mate since the later doesn't work in study motion. then you can go the study motion and the components list you can select the mate you created and with right click you can change the properties. don't forget to take the timing line to 10 seconds.
(2)- Here is the easiest way if you don't want hassle with other components. First,select the component from the window in study motion. Second, move the timing line to 10 second. Third, on the 3D drawing screen right click on the component and choose "Move with Triad" or simply you can click on "v" on your keyboard. Finaaly, rotate the the component around 18 degrees - the scale will be appear - and it is done.
