Hello everyone,
For this equation, I have found Ay as 0.677kN by using Ma = 1.5kN(7m)-Ay(15.5m).
To find Cy, would I be using the sum of forces to find the answer?
For example Fy = Ay - F2 - F1sin55 + Cy = 0
This would then get Cy answer as 2.05kN
The question is to determine the force in the small opening, delivered from the 250 N on both sides of the plier.
i tried multiple things but can't get the answer right. Anyone that could help me?
This is my work so far:
Given that the tibia is 0.6kg and is 35 cm long. The force at the knee (Fk) is: (-200i + 346.41j)N
Find the moment about the ankle due to Fk
I found that: r: rx = (0.35cos60) and ry = (0.35sin60)
Using the sum of moments where: rxFy - ryFx = 0
[(0.35cos60)(346.41)] - [(0.35sin60)(-200)] =...

Regarding part (c) (i), as we know that we can consider any of the convenient point as our pivot. If I consider the point where the 5kg mass (center of mass of the bag) acts, the asnwer turns out to be wrong. The correct answer has 4kg mass as pivot

Assume that a motorcycle of mass m has two wheels that are equidistant from its centre i.e the force on each wheel is m*g/2.
If the motorcycle accelerates forward, will the two forces on each wheel (measured instantaneously) remain the same? If not, how can one mathematically describe the...
I just can't figure this out with the stresses and moments. What is the force required on the handle to get the 850N on top?
