Weight at an angle

My physics knowledge is pretty basic, somebody suggested that I'll get the definitive answer of below question here.

Imagine a barbell of mass m (kg) which is placed on the ground initially,And then it's lifted by a lifter at some angle from the ground. The question is, how much weight is actually lifted by the lifter. So, if the barbell's weight is 20kg and I add one 20kg weight plate to it, then, am I lifting 40kg when I lift it high enough that the bar makes a 30" angle? or, it's less or more.

To be precise, the barbell is lifted like below image. for back workout :).

the end of the barbell which doesn't have plates can be considered touching the ground for simplicity.

• Your question needs clarification. Are you pulling the barbell up a ramp? Commented Oct 11, 2022 at 16:08
• @David - No, the barbell is placed on the ground in like a straight line. Commented Oct 11, 2022 at 16:18

• Welcome @shshank. Is all the weight (20kg or 40kg) at the raised end? How exactly is the lifter holding the barbell: Both hands on the end with the weights or somewhere along the bar? Is the lower end fixed on the ground so it can't move but only rotate? Commented Oct 11, 2022 at 17:06

Note, however, that if the direction of the lift is not optimal, the effective weight could actually be more than than the weight of the plates. For example, in the extreme case of pulling along the bar instead of perpendicular to it, I think it is intuitive that you couldn't get the plates off the ground. If I haven't made any mistake in my mental trigonometry, the vertical component of a force $$F$$ parallel to the bar is $$F\sin{\theta}$$, where $$\theta$$ is the angle of the bar with the floor, so the force needed to lift the weight is $$W/\sin{\theta}$$ which goes to infinity for $$\theta=0$$ and is never less than $$W$$ at any angle. I doubt any landmine exercise has people pulling directly along the bar, but if your pull goes past 90° from the floor (in the vertical plane through the bar) then you are both lifting the weight and trying to pull the bar out of its socket. If the bar was loose in the socket, it should pull out (which could be dangerous), but if the bar is fixed in the socket you'll be exerting a force greater than the weight.
