how to build expression for forward and backward translation motion with specified load?

Hi,
What do you mean by specified load?
you can apply translation motion through Motion panel and write your expressing/function like X*SIN(TIME*360D)

i know load which is acting over slider and right now i am using following expression 'STEP(TIME,0,0,1,-400).

here -400 is end load and 1 is end time . but slider will move up to 0.057 sec.
why is it not converging up to 1 sec?
how to form this expression to both forward and backward?

Hi,
The function looks fine. Can you check if there are any warning or errors about redundancy in log file?
If possible share the .mdl file through personal message.

Hello Prakash Pagadala,
I have problem with setting a sine function. A sine wave can be divided into 2 halves. The 1st half is 0~180 degree while the Y value is positive. The 2nd half is 180~360 degree while the Y value is negative. If I want to create I sine function with different amplitudes for 1st half and 2nd half, how do I create such expression?
For example, there are two sine functions as below：
A1*SIN(TIME*360D) ------- F1
A2* SIN(TIME*360D) ------- F2
0~0.5 sec, I want to use function F1 (namely 1st half of F1)
0.5~1.0 sec, I want to use function F2 (namely 2nd half of F2)
How do I integrate above two expressions into one expression?
Thank you so much for your help!
