8) A 740 N person stands on the high end of a ramp that's tilted up at 35° from due East, 3.1 m along the ramp from the ground-level end of the ramp (the pivot). For r being the displacement from the ground level end of the ramp to where the person is standing and F being their weight, find the torque t=r x F. Make sure the direction of your answer is properly defined.

Consider a uniform ladder of length 4.3 m and mass 10 kg. The ladder is falling over, pivoting about the end that is touching the ground. Someone is pushing on the top end of the ladder with a horizontal force of size 415 N. At the instant when the ladder makes a 46 degree angle with the horizontal, calculate the net torque on the ladder about its bottom end, in N m. Make your answer positive, and use g = 10 m/s2. (Please answer to the fourth decimal place - i.e 14.3225)

A shaft is fixed at support C and has a torque of 75lb.ft with respect to free end at a distance of 0.75ft from C. It remains constant for 0.75ft before a negative uniformly distributed torque of 1200lb.ft/ft at a distance of 1.5ft is introduced. The shaft then remains flat for 1.5ft to free end with a torque of 600lb.ft. where in the shaft is the torque equals to negative 1200lb.ft measured from the free end?
Assume a single 300-N force is exerted on a bicycle frame as shown in the figure. Consider the torque produced by this force about axes perpendicular to the plane of the paper and through each of the points A through E, where E is the center of mass of the frame.

In the design in the figure, a force of Fn=1912 N in the vertical plane and a torque of Md=916 Ncm in the clockwise direction of rotation act on a machine element with a diameter of D=200 mm on the shaft resting on the A and B bearings. If the angle of the force with the horizontal is b=49o, how many Newtons is the resultant radial force to be considered in the bearing calculation of the bearing A? 1-) The diameter of the machine element on which the force acts will not be taken into account in the calculation of the bearing forces (ie, it will be assumed that the Fn force acts on the axis of the shaft). 2-) Pi number will be taken as 3.14.
