Answer:

T=502.5N

Ax=171.8N

Explanation:

The computation of the tension T in the rope and the forces exerted by the pin at A is shown below:

vertical forces sum = Ay + Tsin20 + T - 245 - 883 = 0

Now  

horizontal forces sum = Ax - Tcos70

Now Moment about B

-Ay × 4.8 + 245 × 2.4 + 883 × 1.8=0

Ay=453.6N

Now substitute in sum of vertical forces T=502.5N

Ax=171.8N

Does riding a bike up a hill in higher gear burn more calories than a lower gear
Rasek [7]
Yes. If you are riding a bike up a hill in fifth gear, you will burn considerably more calories than if you were to bike up that hill in first gear. The lower the gear, the easier the pedaling, and therefore fewer calories are burned.
