Basement ceiling - the gym machine is 5 cm too tall!

I join the choir, leave the ceiling alone, cut down the machine.

It should be enough to cut the standing square beam by 2cm to lower the end of the slanted part by 5cm. In the worst case, you might be able to settle for 1cm and bevel the corner of the slanted one.
