Hello, I believe the answer would be 105N as the questions asks "handles". "Handles" being a plural thus each hand would lift half of force By

Mmmmm. Yes I guess the wording of the question is a bit ambiguous. I read it as the total force on the handles as opposed to the force on each handle...

Sorry to be offtopic but does anybody know a tool to get back into an Instagram account..? I was dumb forgot the login password. I would love any tips you can give me.

@Mekhi Wesson i really appreciate your reply. I got to the site thru google and I'm trying it out atm. Seems to take a while so I will get back to you later when my account password hopefully is recovered.

a man exert a force of 200N on wheelbarrow at an angle of 30° above the horizontal. What are the horizontal and vertical Force's exerted on the handle of the wheelbarrow?

The center of mass is shown for the height lifted, so we are just looking at two turning moments. The clockwise moment of the mass 588N over a distance of 0.5m, the equals 294N (588 divided by 0.5). The anticlockwise moment has the 294N divided over a total length of 1.4m (0.5m + 0.9m), this gives 210N. Can this be used as an alternative method?

Hello, may I ask a question : What is the height of the handles when the wheelbarrow becomes unstable?

What would be direction of friction force between the roller and ground (in case coefficient of friction would be given to consider friction force)?

Friction force opposes the direction of motion so it would just depend on which way it was being pushed.

hello, may i ask, where did you get the 9.8 from ? (the first bit of the video) I understand the 60 but not why you multiplied it by 9.8?
@theryderproject5053
@theryderproject5053 3 жыл бұрын
It was to turn the mass (60 kg) into a force (measured in Newton's). Remember that free body diagrams relate to forces not masses. In order to convert, you multiply by 9.8 m/s^2 which is the acceleration due to gravity.

The answer is 105 N since the question asked for each if the handsles😅

why didn't we use the value of 0.6m
@theryderproject5053
@theryderproject5053 4 жыл бұрын
Because it wasn't needed based on where the forces were applied and their directoons. I'd recommend watching the video again.
