I was given this info

r=1.5 m
d=3 m
F= 50 N
angle= 110 degrees

1. What torque is APPLIED ?
T=Fsin
T= (1.5)(50)sin(110)
T=70 N m

2. At what angle would enough force be applied to achieve maximum toque?
T=Fsin
T= (1.5)(50)sin(10)
T=13.0 N m

3. If someone continues to push with a force of 50 N, what maximum torque could be applied?

T=Fsin
T= (1.5)(50)sin(90)
T=75 N m

Are these solutions to the questions correct, if not; what do i need to change to get the correct solution?
