- 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 2.1 cm from the elbow, how much force must the biceps exert to hold a 35 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.A uniform ladder 10.o m long weighing 50.0 N rests against a smooth wall (no frictional force between ladder and wall). If the coefficient of static friction is .360 and makes a 60 degree angle with respect to the horizontal, what is the frictional force and how far along the ladder can a 70.0 kg painter climb before ladder begins to slip?need help and steps to solve this
- A 368.6N tightrope walker stands at the center of the rope such that each half of the rope makes an angle of 5 degrees with the horizontal. What is the tension in the rope?3. Consider the system shown. A 5.00 m beam supports a mass of 3000 kg attached to a cable. The mass of the beam is 1000 kg. Assume that the mass of the beam is uniformly distributed throughout its length. (a) Determine the tension in the cable (b) Calculate the horizontal and vertical components of the force exerted at point O. 5.00m 3000 kg 45.0°Look at the figure below. The horizontal beam weighs 200N, Find the tension in the cable if the object hanging on it is 350N. (Note: its center of gravity is at its center)
- The horizontal beam inFig weighs 190 N, and itscenter of gravity is at its center.Find (a) the tension in the cable and(b) the horizontal and vertical componentsof the force exerted on the beamat the wall.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 2.4 cm from the elbow, how much force must the biceps exert to hold a 42 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.With three decimal places
- Lifting heavy furniture is a lot of work. To make things easier, movers use dollys to take advantage of the rolling movement. However, sometimes the mover can't even lift the object to get the dolly under it. That's where the dolly comes in. Assuming the refrigerator is 200N and the pry bar is 12" long and makes 30 degrees angle with the floor, what is the Net Force necessary applied straight down to lift up the fridge? What if the pry bar was 36" long?Responses/submit?d... tleb USCIS | U.S. Citizens... 4 Google Drive Ebooks Z-Library * Cengage C Get Homework Hel... Google Jamboard >> Go A beam resting on two pivots has a length of L = 6.00 m and mass M = 84.0 kg. The pivot under the left end exerts a normal force on the beam, and the second pivot placed a distance l = 4.00 m from the left end exerts a normal force n,. A woman of mass m = 63.0 kg steps onto the left end of the beam and begins walking to the right as in the figure below. The goal is to find the woman's position when the beam begins to tip. (a) Sketch a free-body diagram, labeling the gravitational and normal forces acting on the beam and placing the woman x meters to the right of the first pivot, which is the origin. (Do this on paper. Your instructor may ask you to turn in this work.) (b) Where is the woman when the normal force n, is the greatest? 1 typica This answer has not been graded yet. y and inte ject and X W 81°F Mostly cloudy
