Hey I am getting an error in the Section 8.1, task 9 of the Simscape Onramp course. I re-did the entire line of tasks with accordance to the solution but still it wasn't resolved.
Can someone please help me ASAP?

Try to change a unit of the inertia.

Hey Sankalp,
I understand that you are facing value miss match while plotting the “Inertia”values against the expected Signal requirement in Simscape onramp section 8.1, task 9.
Please know that this issue occurred as “Inertia” block is not connected properly in your system model as it can be seen in the screenshot you provide that there are no values plotted for “My signal” data.
To resolve the requirement for the task, do the following:
- Connect the “Inertia” block to the “Gear box” block.
- Submit the task.
Here are images attached for both the error and correction for your reference.
