Chapter 6, Problem 73EAP
A block of mass m is at rest at the origin at t = 0. It is pushed with constant force F0from x = 0 to x = L across a horizontal surface whose coefficient of kinetic friction is µk= µ0(1 −x/L). That is, the coefficient of friction decreases from µ0at x = 0 to zero at x = L
a. Use what you've learned in calculus to prove that
b. Find an expression for the block's speed as it reaches position L.

- A bicep muscle shown in Fig. P2.3 can apply a force F measured in Newtons (N) as a function of the elbow angle ϕ, measured in degrees as described by the quadratic equation F(ϕ) = 6ϕ − 0.04ϕ2. For a bicep force of F = 200 N, solve the equation for ϕ by each of the following methods: factoring, completing the square, and the quadratic formula. Using your solution from part (a), determine the elbow angle ϕ where the force exerted by the bicep is maximum. In addition, calculate the maximum force Fmax. Plot F versus ϕ and clearly indicate the maximum force on the graph. Also clearly label the x-intercepts on the graph.arrow_forwardA force P= 696 KN whose line of action passes through points A(3, 2, 1) and B(7, 7, 10). Determine the y-component of force P in kN.

Three forces act upon the block: F→w, the force of gravity: F→n, the normal force; and F→f, the force of friction. The coefficient of friction is large enough to prevent the block from sliding. Because the block is not moving, the sum of the y components of the forces acting on the block must be zero. Find an expression for the sum of the y components of the forces acting on the block, using coordinate system b. Because the block is not moving, the sum of the x components of the forces acting on the block must be zero. Find an expression for the sum of the x components of the forces acting on the block, using coordinate system b. To find the magnitude of the normal force, you must express Fn in terms of Fw since Ff is an unknown. Using the equations you found in the two previous parts, find an expression for Fn involving Fw and θ but not Ff.arrow_forward
