Public static void subswap(btnode root) // precondition: root is the root reference of a binary tree. // postcondition: if root is non-null, then the original left subtree below // this root has been moved and is now the right subtree, and the original // right subtree is now the left subtree. // example original tree: example new tree: // 1 1 // / \ / \ // 2 3 3 2 // / \ / \ // 4 5 4 5

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
