1. A uniform horizontal bar of length L = 2.0 m and weight 144 N is pinned to a vertical wall and supported by a thin wire that makes an angle of 0 = 150 with the horizontal. A mass M, with a weight of 302 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 573 N. What is the maximum possible distance from the wall at which mass M can be placed...

#4 please
A uniform sheet of metal in the shape of a hemisphere of radius 1 m is used as a sign. The hemisphere has a mass of 200 kg and is suspended by two vertical wires attached to points along its horizontal diameter. One wire is attached to the left end of the diameter and the other is attached to a point three-quarters of the way to the other end. What is the tension in each wire? A ladder...

Problem 4: (Robot strength scaling effects) - all students, G-15 pts- UG 25 pts 1) Consider a four legged "microrobot" consisting of a cubic body, and four single dimensional "legs" arranged in the corners as shown in Figure 1. Assume that the legs are passive, e.g. they flex to support the weight of the robot (Figure 1 shows the robot at the moment it is placed on the ground). Assume that the dimensions of the legs and body are proportional,...

Consider the ladder in 8.15. Compute the normal force again,
assuming a 75 kg man is standing on the ladder (a) at its midpoint
and (b) four fifths of the way up the latter.
I posted this question earlier but was very confused on how it
was answered and laid out. I am not understanding how to go about
this or what formulas to use.
