Question

9.36. Refer to Fig. 9-36. The angle of static friction between the block with mass $M$ and the plane is $\phi$. For the angles shown in the figure, what is the expression for the force $P$ to move the block up the plane? Ans. $P = \frac{9.8M \sin(\theta + \phi)}{\cos(\beta - \phi)}$ 9.37. In Problem 9.36, show that the minimum value of $P$ for a given angle $\theta$ is $9.8M \sin(\theta + \phi)$.

9.36. Refer to Fig. 9-36. The angle of static friction between the block with mass M and the plane is phi . For the angles shown in the figure, what is the expression for the force P to move the block up the plane? Ans. P=(9.8Msin( heta +phi ))/(cos(eta -phi )) 9.37. In Problem 9.36, show that the minimum value of P for a given angle heta is 9.8Msin( heta +phi ). 9.36. Refer to Fig.9-36.The anglc of static friction between the block with mass M and the plane is .For the angles shown in the figure,what is the cxpression for the force P to move the block up the plane? Ans.P=[9.8M sin(0+]/[cos(-)] 9.37. In Problem 9.36,show that the minimum value of P for a given angle is 9.8M sin+ Fig.9-36
