Calculate the back extensor force (Fm) required to keep the trunk in the static position as shown. Report Fm, in units of N, to 0 decimal points (e.g. 101 N). Report only positive values (i.e. the absolute value). You are allowed an error margin of +/- 10 N from the exact correct answer. The spine and back extensor muscle (Fm) are aligned horizontally with the floor. The ground reaction force (GRF) under the hand is aligned vertically. You only need to consider the weight of the trunk (disregard the head and arms). Here is information you may need to solve this problem: • The GRF is 195 N. • The GRF has a moment arm of 0.4 m relative to the vertebra axis of rotation. • The weight of the trunk is 303 N. • W trunk has a moment arm of 0.29 m relative to the vertebra axis of rotation. • Fm has a moment arm of 0.06 m relative to the vertebra axis of rotation.arrow_forward

In a static-pulley system, the net force on individual pulleys may be non-zero. If a rope passes around many ideal pulleys, the tension may be different at either end of the rope. Using pulleys, it is possible to lift a box of weight mg using a tension T < mg If there is more than one rope in a pulley system, then each rope may have a different tension. If a rope passes over an ideal pulley, the tension is larger on one side than the other.arrow_forward

I managed to calculate that: slip angle is θ= 21.8 degrees acceleration is 1.09 m/s^2. I am trying to find: Let the angle θ be the angle you calculated , θslip (21.8 degrees) . To keep the block from slipping, you apply a horizontal (parallel to the surface of Earth) force directed to the right on the block. Your horizontal force F→Yb has a magnitude of 45 N. Calculate the magnitude and direction of the force due to static friction for this new situation, assuming that the block does not slip. Enter a magnitude for this part, but consider what the sign of your answer tells you about the direction of the force.arrow_forwardProblem: A block is resting on a ramp as shown in the figure below.
