Dogs, like many animals, stand and walk on their toes. (Figure 1) shows the rear foot and leg of a 20kg dog along with the relevant distances and angles. The Achilles tendon pulls on the heel at an angle 15° from vertical. Part A What is the tension in the tendon if the dog is supporting one fourth of its weight on each foot? Express your answer with the appropriate units. F = N CalfmuscleAchillestendon15\deg 45\deg 9.0 cm 4.0 cm Calf muscle Achilles tendon -15° -45° 9.0 cm 4.0 cm

Please solve it in a handwritten format with a free body diagram. Don't use chat gpt. (Diagram is mandatory) Mechanical engineering -

Static Equilibrium of a rigid body. The left picture of the rigid body is the initial, the right picture is the final. Complete the calculations of all the quantities in the data table. Check to see if each of the equations of equilibrium is satisified. Use the blue filled out information to help you get the data for the other parts.

Please help. Written on paper not typed on computer or keyboard please. Need help on both questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

Help!!! Please answer part B correctly!!! Please

Pls.help with 24.

Below is a diagram of a human arm. 5.0 cm F M -15 cm- Ꮃ . A -35 cm- W B The forearm is lifted by the biceps muscle, which is attached approximately 5.0 cm from the joint. Champion athletes are often found to have muscle attachments farther from the joint than the average person (5.5 cm). (a) Why does this small change in the muscle attachment position give an advantage when lifting or throwing? Explain clearly, referring to the above diagram.10 108

Sketch the system described above and answer the following, expressing your answers with 3 significant digits. a. What is the length of the ladder? b. How far from the wall is the foot of the ladder? c. What is the angle between the wall and the ladder? d. What are (a) and (b) in meters?

Mechanical engineering thermodynamics. Handwritten solution accepted. (3-150) In an article on tire maintenance, it is stated that tires lose air over time, and pressure losses as high as 90 kPa (13 psi) per year are measured. The article recommends checking tire pressure at least once a month to avoid low tire pressure that hurts fuel efficiency and causes uneven thread wear on tires. Taking the beginning tire pressure to be 220 kPa (gage) and the atmospheric pressure to be 100 kPa, determine the fraction of air that can be lost from a tire per year.
