The Achilles tendon force Ft is mobilized when the man
Chapter 4, Problem 4-16(choose chapter or problem)
The Achilles tendon force \(\mathbf{F}_t\) is mobilized when the man tries to stand on his toes. As this is done, each of his feet is subjected to a reactive force of \(N_t = 400\ N\). If the resultant moment produced by forces \(\mathbf{F}_t\) and \(\mathbf{N}_t\) about the ankle joint A is required to be zero, determine the magnitude of \(\mathbf{F}_t\).
