A uniform beam resting on two pivots has a length L = 6.00 m and mass M = 76.5 kg. The pivot under the left end exerts a normal force nt on the beam, and the second pivot located a distance l = 4.00 m from the left end exerts a normal force nz. A woman of mass m = 56.7 kg steps onto the left end of the beam and begins walking to the right as in the figure...
A uniform beam resting on two pivots has a length L=6.00m and mass M =88.9kg. One pivot supports the left end of the beam and the second pivot is placed at distance ℓ=4.00m away from it. A woman of mass m=57.3KG steps onto the left end of the beam and begins walking to the right as in the figure below. Find the position x of the woman when the beam is about to tip. Define the origin (x=0) as the...
Need help with part C. Thank you!
This is the figure above. However, it has different values than
the homework question above.
PRACTICE IT Use the worked example above to help you solve this problem. A woman of mass m = 53.6 kg sits on the left end of a seesaw-a plank of length L = 4.39 m, pivoted in the middle as shown in the figure. (a) First compute the torques on the seesaw about an axis that passes...
I need help with exercise and practice it.

Use the worked example above to help you solve this problem. A woman of mass m = 54.5 kg sits on the left end of a seesaw—a plank of length L = 3.50 m—pivoted in the middle as shown in the figure. (a) First compute the torques on the seesaw about an axis that passes through the pivot point. Where should a man of mass M = 75.3 kg sit if the system (seesaw plus man and woman) is to...

A uniform ladder stands on a rough floor and rests against a
frictionless wall as shown in the figure.
Since the floor is rough, it exerts both a normal force
N1
and a frictional force
f1
on the ladder. However, since the wall is frictionless, it
exerts only a normal force
N2
on the ladder. The ladder has a length of
L = 4.85 m,
a weight of
WL = 62.5 N,
and rests against the wall a distance
d...
Can you help finish drawing the free body diagram for question
#5?
Also I need help with #6 for calculating torque and filling in
the table.
I will rate thank you!
Name: Balance Lab (Part 1) Date: Explore the "Balance Lab" section of the Balancing Act simulation. 4. Create a situation in which the beam is balanced (without the supports) while there is a single collection of bricks on one side of the pivot and two different collections of bricks...
Need help on E through I.
Static Equilibrium Exercise A 142 m long ladder that weighs 485 N is resting against a very slimy wet moss covered wall that can be considered to be frictionless, as shown in the figure hbelow. A fire fighter that weighs 795 N is 5.64 meters up the ladder 5.6 m 60.0 a . Identify and label all the forces acting on the ladder. o. Make a list of the x-components of the forces acting...
Question 8 please-show all work
You are building a mobile. It is connected to the ceiling by a rope. The hanging weights are attached to a massless beam. Use L = 0.25 m, D = 0.5 m, M_1, = 1 kg and M_2 = 1.5 kg. You have a third mass M_3 = 2 kg. Determine the tension in the rope connecting the beam to the ceiling and the location where you attached M_3 if you correctly placed it so...
