Gravitational field strength (GFS) on earth =10 N/kg
Weight = GFS x mass
W = 10 x 7
W = 70N
70N = 15.74 pounds
Answer:
Fs = 32N
Fh = 21 N
Explanation:
Statics
Let Fs be the force of the shoulder, assumed upward
Let Fh be the force of the hand, assumed downward
Sum moments about the hand to zero
1.1(9.8)[67] - Fs[22.5] = 0
Fs = 32N
Sum vertical forces to zero
32 - Fh - 1.1(9.8) = 0
Fh = 21 N
Or we could sum moments about the shoulder point
1.1(9.8)[67 - 22.5] - Fh[22.5] = 0
Fh = 21 N
