2. For this series of 4 questions, a man sits in the chair which is pin-connected to the
10-m frame BC. Frame BC rotates counterclockwise. Your final goal is to determine
the magnitude of the support force N exerted by the chair on the man at the instant
0 = 30°. But before that, you need to answer some other questions. Please pay
attention: the numbers may change from problem to problem since they are
randomized.
3) If the two unknowns, N and N₁, represents the tangential component and normal
component of the support force N respectively, and the man has mass of m, select
the correct equations of motion that, when used together, can solve for the support
force N exerted by the chair on the man at the instant = 30°. Take g = 9.81 m/s².

In Part B, it was shown that the tension in a cable is constant around a frictionless pulley. The reason why the equations of equilibrium could be used here is because the
values of 0 and o are not arbitrary. In fact, the geometry of the system is based on the equations of equilibrium and a relationship between 0 and o can be determined
using them.
Part D - Finding the relationship between \theta and \phi
Figure
Find the relationship between angles e and o using the equations of equilibrium and solve for 0. Suppose that the angles are expressed in radians.
Express your equation for 0 in terms of ø. Express your answer in radians.

Recall that muscle generates force at 30 N/cm?. Two cross sections are taken from the rectus femoris
muscle (bipennate muscle similar to the diagram below). The length and width of the first cross
section is 6 cm and 5 cm respectively with a 35° angle of pennation. The length and width of the
second cross section is 5.6 cm and 3 cm respectively with a 31° angle of pennation. What is the
predicted maximum tendon force (FTendon) of this muscle in Newtons? Answer to the nearest 0.1 N.

You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?
