What is the maximum load for this crane at an angle of 31.0 ◦ with the horizontal? Answer in units of N.
7416.26 N*M as the torque capacity.
Torque is given by the equation
T = F * D = F * L * cos(∅) (1)
where T = the torque (7416.26 Nm as max for this case)
F = the force exerted (max force for a max torque)
D = the distance (m) from the axis of rotation, perpendicular to the force
L = the moment are of rotation (length of the crane boom, in this case)
∅ = the angle between D and L (31o in this case)
("... for this crane ..." suggests that a missing diagram shows the length of the boom.)
Solve equ (1) for the Fmax and plug in the numbers.
