- When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.60 kg. If the biceps is connected to the forearm a distance of 2.2 cm from the elbow, how much force must the biceps exert to hold a 39 N ball at the end of the forearm at distance of 36.0 cm from the elbow, with the forearm parallel to the floor, in Newtons? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.⦁ Imagine that you hold a 6.0kg lead ball in your hand with your arm bent. The ball is 0.35m from the elbow joint. The biceps muscle attaches to the forearm 0.050m from the elbow joint and exerts a force on the forearm that allows it to support the ball. The center of mass of the 12N forearm is 0.16m from the elbow joint. Estimate the magnitude of⦁ The force that the biceps muscle exerts on the forearm ⦁ The force that the upper arm exerts on the forearm at the elbowFind the x and y-coordinates of the center of gravity of a 4.00-ft by 8.00-ft uniform sheet of plywood with the upper right quadrant removed as shown in the figure below. Hint: The mass of any segment of the plywood sheet is proportional to the area of that segment.

Tom is sitting 2 feet from the right end of the see-saw. The pivot for the see-saw is 6 feet from the left end. The see-saw is in balance horizontally. What is Tom’s weight?Question 1 25 A 380 kN horizontal force P is applied to a 210 kN box resting on an 25° incline. The line of action of Ppasses through the center of gravity of the box. The box Is 3.5 m wide x 3 m tall, and the coefficents of friction between the box and the surface are 14 -0.6 and 14% -0.51. Determine the magnitude of the friction force acting on the box. F'= The box is In static equilibrium Sliding up the incline Sliding down the incline. ○ TippingA.) what is the torque by the weight of your upper body considering sacrum as the pivot, in lb·m?
